Jan 6, 2023 · For example, as a result of my initial Big Y-500 test, I got the terminal SNP R1b-FGC36974. Then a fifth cousin of mine also did the Big Y-500. He and I both went to R1b-FGC36982, one step downstream of FGC36974. Subsequently, another fifth cousin did the Big Y-700 when it first came out. He also landed at R1b-FGC36982.

Nov 7, 2024 · I am confused by my Big Y results. I have two matches which at Y-111 show 6 steps and 5 steps difference. But at Big Y the numbers are reversed and they show 5 of 687 and 8 of 609. The TiP calculator at Y-111 suggests MRCA at 1600 and 1650 repectively, but I can't find a way to predict the MRCA based on the Big Y results.

2) Since the Big Y finds roughly one SNP per 150 years of patrilineage, you will find your true terminal SNP only when someone rather closely related to you also orders the Big Y. But once you have your Big Y results, you are essentially done with your own Y chromosome testing--you "merely" have to convince others to order the test too.

The customers who are purchasing Big Y-500. They will get the results like the (old) Big Y test before and all STR panels (1-6) = STRs 1-561. "customers do not have to have a Y-STR test already before purchasing the Big Y-500 since it contains the Y-111. Big Y without STRs will no longer be available."

If you'd like to get the lowest price for Big Y, wait until the holiday sale, which goes from mid-November to Dec. 31. For the last three years, FTDNA has included Big Y in the sale. The regular price for Big Y is $575, but during the sale the price is $525.

Jun 16, 2020 · The Big Y-700 price was reduced last year permanently by $100, but without the BAM file, because most people didn't use it. If you want or need it, you pay the additional cost. As mentioned above by dtvmcdonald, you can download the VCF (Variant Call File) and BED files. Otherwise, you get the same information in your account (Block Tree, novel ...

Jun 19, 2020 · This article by Roberta Estes may be of some help: "Family Tree DNA’s New Big Y Block Tree." This is from Jan. 2019, and refers to Big Y-500 and a tutorial. I do not see a tutorial any more, and of course we are now up to Big Y-700, but otherwise not much else has changed (the "Origins" ring shown in the article no longer appears).

Aug 2, 2021 · FTDNA has started a Summer Sale, starting today, Monday 2 August, and going through until Tuesday, 31 August. There is sale pricing on Y-DNA, mtDNA, and Family Finder tests, for single products, bundles, and upgrades. The link to the sale is on the FTDNA home page (https://www.familytreedna.com).

Oct 3, 2020 · So, Roberta Estes performed two comparisons, and derived average mutation rates of 54.25 years and 65.6 years for the Big Y 500 product. Both of these observations would be outside the 95% two-sided confidence interval under the Adamov distribution, but under what I'll call the Xue distribution, they come within 1% and 18% respectively.

We ask members with Big Y results (currently 756 members) to upload their raw data (VCF/BED files) to the files section of our Yahoogroup for use in the spreadsheet. Almost 90% of the members with Big Y results have done this. The spreadsheet is far superior to the post-Big Y analysis that FTDNA gives its customers, just as Alex's tree is superior.
