Password » Forgot Password? You’ll recall that as a result of the Big Y test, BY18350 was split and now has three child branches plus one person whose terminal SNP is BY18350. You can read an overview of Y DNA, here, and Y DNA: The Dictionary of DNA, here. The Big Y-700 test is most valuable for individuals who have solid paper trails and traditional Y-DNA testing that matches others going back at least eight generations. John Smith 1700-1750 won’t do it, but Seamus McDougal (1750-1810) married to Nelly Anderson might just work. Static files pro… The mathematical term Y = f (x), which translates as simply “ Y is a function of x,” illustrates the idea that the important process outcomes (Y s) are a result of the drivers (x ‘s) within processes. 0 comments. If some of the private variants in the closer branches disappear, then the common ancestral branch may shift to closer in time. On the Big Y AND at least one level of STRs between 12 and 111, inclusive, On STRs to someone who has taken the Big Y test, but whom you do not match on the Big Y test, Select only men that match on the Big Y in the STR panel, Add an option for Big Y on the advanced matches page, Indicate men who also match on STRs on the Big Y match page, Last Name – You will want to search matches on your personal page at. Haplogroup information about men who took the M222 test and whom the tester doesn’t match at all are shown here as well in the country and branch totals for R-M222. xD. 1725, d. 14 Aug 1761 NY and Rachel Haff. 0 followers. Our ancestors may have been at Knowth and New Grange, and yes, perhaps even at Tara. and shows how far this has all come. To the right of the haplogroup-defining SNP are listed the branch and equivalent SNP names. Which Y-chromosome test(s) would be appropriate to prove the relationship? Matches report could be added like on Block Tree. The best thing to do next with your results is to join a surname project. On my reconstructed Match/Block/Haplotree, I included the estimated SNP generations as well. His descendants include our McNeil ancestors, who still slumber someplace, awaiting discovery. I have only 5 matches at 111 markers, with the closest being at a G.D. of 6, and 2 of these match me on the BigY700 and are downstream from me. This test examines thousands of known branch markers as well as millions of places where there may be new branch markers. Post was not sent - check your email addresses! I do have a few questions, that I hope you can answer: – Within the SNP maps, I have the same “location” for all of my upstream SNP’s, so for example, R1B-BY651 is Derry, R1B-L193 is Derry. I’d suggest you simply read this article the first time to get a feel for the landscape, before working through the process with your own results. We can only achieve approximations, but those approximations improve as more people test, and more SNPs are named and placed in their proper places on the phylotree. Elsewhere, it was reported that the McNiel brothers sailed from Glasgow, Scotland and that George had been educated at the University of Edinburgh for the Presbyterian ministry but had a change of religious conviction during the voyage. If you happen to also match on STRs, their haplogroup is shown there as well. If this age is even remotely accurate, averaging by 80 years per generation often utilized for Big Y results, produces an age of 2000 – 4720 years. I expected to find a McNeil who does match on at least some STR markers. You might not know in which generation you connect, but you’ll have a range of a few generations to start your search. That’s not surprising since Big Y matching reaches further back in time than STR testing, and indeed, not all STR testers have taken a Big Y test. After my McNeill cousin’s Big Y results came back from the lab, I spent a significant amount of time turning over every leaf to extract as much information as possible, both from the Big Y-700 DNA test itself and as part of a broader set of intertwined genetic information and genealogical evidence. It’s very unlikely that the mutation occurred in Niall’s generation, and much more likely that other men carried M222 and shared a common ancestor with Niall at some point in the distant past. The Big Y test gives testers the best of both, along with contributing to the building of the Y phylotree. R-M222, the SNP initially thought to indicate Niall of the 9 Hostages, occurred roughly 25-59 SNP generations in the past. See more . For example, you’ll see that it’s 70.93 percent likely that you and your match on 65 out of 67 markers share an ancestor at or before six generations. This can be seen by looking them up on YBrowse..I’ve only observed them placing them on the Haplotree, however, AFTER they match another tester. Let’s take the odd shaped one for the ride. Express the maximum number of operations, the algorithm performs in terms of n. Eliminate all excluding the highest order terms. Many of the techniques and processes of data analytics … One point you made which I think is very important is that FTDNA might wish to consider increasing its maximum threshold of 30 non-matching variants when determining matches; especially given the precision of the recent Big Y 700 test. Technology-savvy organizations, as well as “digital non-natives,” can benefit from analytics and augmented intelligence across all disciplines by using an infusion strategy. This means the Big Y test will find unique Y-DNA variants that only your specific paternal line carries. In other words, Cousin McNeill’s terminal SNP, meaning the SNP furthest down on the tree, R-BY18332, is also his haplogroup name. In your situation, a basic 10- to 15-marker test would probably be sufficient to determine whether you’re related to your suspected cousin. If the Ui Neill dynasty was represented in the persona of the High King, Niall of the 9 Hostages, 1600 years ago, his M222 ancestors were clearly inhabiting Ireland earlier. SNPs and haplogroups reach back infinitely, and can be tracked historically beyond the genealogical timeframe, shedding light on our ancestors’ migration paths, helping to answer the age-old question of “where did we come from.”. That’s because you’re simply looking for a haplotype match, rather than trying to estimate the number of generations back to a common ancestor. Remember, a non-matching variant means they do NOT match the tester’s mutation. (Haplotype is the term for a set of Y-DNA test results.) These two types of tests, STR panels 12-111 and the SNP-based Big Y, are meant to be utilized in combination with each other. They all have those same private variants in their non-matching variant list. This subscription provides analysis of your BigY VCF/BED data and shows your position on our leading-edge Y-tree. While I did expect STR matches to also match on the Big Y, I don’t expect the Big Y matches to necessarily match on the STR tests. Big Y Foods, Inc. - SWOT Analysis examines the company's key business structure and operations, history and products, and provides summary analysis of its key revenue lines and strategy. But yet, generally, I’d attribute it to the propensity of the STRs to mutate more often and also backward and forward, both. News; Impact; Our team; Our interns; Our content specialists; Our leadership; Our supporters; Our contributors; Our finances; Careers; Internships ; Contact. I hope FTDNA will add three display options: It was cumbersome and frustrating to have to view all of the matches multiple times to compile various pieces of information in a separate spreadsheet. Matching Both the Big Y and STRs – No Single Source. Of my McNeill cousin’s closest Big Y matches, we find the following relative to STR matching. The profile contains a company overview, key facts, major products and services, SWOT analysis, business description, company history, financial analysis, recent developments as well as key employees. Multiple combined reads of A and G, for example, in the same location, would be tough to call accurately and would be considered unreliable. The part that confused me so badly that I needed a video chat with Göran last week is that in the Block Tree, equivalent SNPs are stacked vertically, giving the appearance of being additional steps, or actual generations, when that’s not necessarily the case. I simulated this functionality in a spreadsheet with my McNiel cousin, a Riley match, and an Ocain match whose terminal SNP is the convergent SNP (M222) between Riley and McNiel. SNPs very rarely experience this level of instability. With fewer matches, it should be a breeze. Unfortunately, this Campbell male does not match the Clan Campbell line, so that momentary clan connection theory is immediately put to rest. Clicking on the link to the Block Tree in the Big Y results immediately displays the tester’s branch on the tree, below. In some cases, Hadoop clusters and NoSQL systems are used primarily as landing pads and staging areas for data. What Browser are you using? Big Y testing not only answers genealogical questions, it advances science by building out the tree of mankind too. A: Your situation is an ideal application of Y-DNA testing, especially since you’ve already developed a theory to test. Niall of the 9 Hostages was reportedly a High King of Ireland sometime between the 6th and 10th centuries. Cannot tell if person is Big Y match or STR match, or both. The re-visit is refreshing …. That means if a tester has a Private Variant and it does not show on the non-matching variant report with a match, it could be because they both have that mutation OR that the match’s test didn’t report a value for that Private Variant. Someday, I will have Big Y matches and will explore these possibilities! No other known McNiel descendants from either Thomas or George have taken the Big Y test, so I didn’t expect any to match, but I am interested in other men by similar surnames. As the name suggests, the Big Y test examines DNA on the Y chromosome, which only men have. For example, the Countries tab for S673 is shown above. One additional note about the non-matching variant lists because if a Private Variant doesn’t show on the list with a match it doesn’t necessarily mean the two men have the same value for that variant. Individually tested SNPs are still occasionally available in some cases, but individual SNP testing has generally been eclipsed by the greatly more efficient enriched technology utilized with Big Y testing. Big Y Pasteurized Cream Cheese. The Big Y test and upgrade at FamilyTreeDNA provides testers with all 111 traditional STR markers, plus another 589+ STRs available only in the Big Y test, plus a scan of the balance of the rest of the Y chromosome that is useful for genealogy. Y-Full, very explicitly defines their close and distance match criteria as: "Close matches" are defined as matches with a genetic distance of less than 0.1, and "Distant matches" as matches with a genetic distance of 0.1 to 0.2. But the Big Y is like a jungle safari. It could also be that the SNP matching threshold needs to be raised since the enhanced and enriched Big Y-700 technology now finds more mutations than the older Big Y-500. The more markers the test evaluates, the higher its resolution. If you don’t wish to combine the two, then you don’t need this column. The Big Y-700 includes the traditional Y DNA STR marker testing along with SNP results that define haplogroups. No, but can click through to profile card, By STR panel only, would like complete download with 1 click, also if Big Y or FF match, No, but would like to see matches haplogroup and convergent haplogroup displayed, No, would like the path to convergent haplogroup displayed as an option, No, see combined match-block -haplotree in next section, Born 1800 Country Antrim, Northern Ireland. I’ve been using SNP tracker. Velocity refers to the rate at which data are generated and the speed at which it should be analyzed and acted upon. Clearly, RM222 is the most prevalent in Ireland, followed by Scotland. One of the biggest benefits of joining a surname project is the assistance of an administrator. The Haplogroup R-M222 DNA Project, which studies this particular haplogroup, reads like a who’s who of Irish surnames. Hello Roberta, thank you for the very informative article – it greatly assists my understanding of all the various concepts around Y testing. Google Analytics lets you measure your advertising ROI as well as track your Flash, video, and social networking sites and applications. Finding a male from the homeland might point the way to records in which I could potentially find baptismal records for George about 1720 and Thomas about 1724, along with possibly John, if he existed. In the graphic below, you can see that M222 has a very large number of equivalent SNPs, which will likely become downstream haplogroups at some point in the future. I also added the SNP generations in red for that haplogroup, at far left, to get some idea of when that common ancestor occurred. Those surnames were: Notice that I said, “were.” That’s right, because shortly after the results were returned, based on markers called private variants, Family Tree DNA assigned a new haplogroup to my McNeill cousin. Conversely, subclades have been born since a common ancestor clade whose descendants haven’t yet tested. These tests correspond to two different kinds of DNA markers, called STRs and SNPs: The Big Y really shines because of its SNP analysis and exploratory nature. Are you aware if FTDNA might actively be considering such a modification to their methodology? I am still a long way from figuring out how I connect with the very few matches that I have. My McNeill cousin agreed to take a Big Y test, and this analysis walks through the process of understanding what those results are revealing. Searching my STR download spreadsheet for similar surnames, I discovered several surname matches, mining the Earliest Known Ancestor information, profiles and trees produced data as follows: Our best clue that includes a Big Y and STR match is a descendant of George Charles Neil born in Tranent, Scotland, in 1747. Certainly not enough to explain an Hg of three men with an average of 9 PV’s one member of which has none. Personalized health review for Big Y Butter Popcorn: 160 calories, nutrition grade (C plus), problematic ingredients, and more. Resolution is measured in ‘markers,’ or locations on the Y-chromosome. (in a good way). The 30 SNP threshold precludes some matches. Often your project administrator will be able to help with understanding your Y-DNA results and how they fit in with the rest of the group. These are the largest companies by revenue. 2019 Mar 16;1-35. doi: 10.1007/s00521-019-04095-y. The report covers the company's structure, operation, SWOT analysis, product and service offerings and corporate … Does the McNiel line have a unique haplogroup, and if so, what does it tell us? Then in the parent group of the other three, BY18350, we find Glass from Scotland. After all, the Big Y is testing for more deep-rooted history. This 67 marker Matches Map shows the locations of the earliest known ancestors of STR matches who have entered location information. Even if you remove some of the variants in the lower generations that are based on an average number of individual variants, you’re still about 1200 years in the past. The Big Y-700 test is the most complete Y DNA test offered, testing millions of locations on the Y chromosome to reveal mutations, some unique and never before discovered, many of which are useful to genealogists. The three child branches on which the tester has matches are shown with red arrows. It’s possible that when they are assigned that they will be placed upstream someplace, meaning that placement will reduce the number of early branches and perhaps increase the number of older branches. A: While autosomal DNA testing is valuable and has helped countless genealogists find their families, it has two glaring flaws: It’s shortsighted and it’s blurry. and analysis, Bill Dick. Are you saying that they don’t match him because those private variants are also on their lists? You can’t tell one way or another if someone shown on the Block Tree is shown there because they are a Big Y match or because they are an STR match that shares the same haplogroup. The Y haplotree will be displayed in pedigree style, quite familiar to genealogists. (The all have the same surname and they all also match him on the Y111 at a GD of 3 or 4). Q: What is the Big Y-700 test offered by Family Tree DNA? I just received my results and am now the 3rd person on the Carnes line you mentioned above. This SNP generation difference between views is a function of dealing with aggregated and averaged private variants on combined lines and causes the SNP generations to shift. Roberta, Non matching variants mean they don’t match. I have no matches for my terminal SNP. Khan Academy is a 501(c)(3) nonprofit organization. That’s what I chose to do after downloading my cousin’s 14,737 rows of STR matches. I have asked that they consider the following: “”””Perhaps there could be a graded matrix presented, much in the same way as is used for STRS: — For example, both men matching in the Big Y500 up to 30 NMV are deemed as matches. Great explanation of these complex issues, Roberta. Taking the Big Y-700 test provided granularity between 6 matches, shown above, who were all initially assigned to the same branch of the tree, BY18350, but were subsequently divided into 4 separate branches. After my head started spinning from uncanny similarity of the several names you mentioned along the way as matches to your cousin, I checked JN’s Y-25 listing and found a significant presence of R-BY18322. In the example above, it’s between 9 and 14 SNP generations. One is a match who lists “Elder George McNeill” as his EKMA. Additionally, the McNiel DNA was assigned to haplogroup R-M222. You can’t change the SNP maps. Using NGS (next generation sequencing) scan technology, the targeted regions of the Y chromosome are scanned multiple times, although not all regions are equally useful. However, today, these equivalent SNPs push M222 from 25 generations to 59. Because of the fact that private variants don’t occur on a clock cycle and occur in individual lines at an unsteady rate, we must use averages.
