For all practical purposes, from a MyHeritage autosomal test, I was able to extract from the 3495 Y-SNPs covered by the chip used, 49 SNPs appearing in the clades downstream of R-U106: *RSID* *Name*

Hi Ewenn, You previously produced a map for FGC13326. I would be curious to see an updated map to see if there are any changes! Thanks -- Kevin Terry

Thanks John. Given that I'm applying statistics to small numbers, we come pretty close to the expected distribution. # SNPs # occur freq 300 yr prob 0 0 0% 0% 1 0 0% 1% 2 0 0% 2% 3 0 0% 5% 4 1 1% 8% 5

Hi Mike, Debbie, As an answer, this link to the ISOGG website: https://isogg.org/wiki/Autosomal_DNA_testing_comparison_chart The number of Y-SNPs included in MyHeritage autosomal tests would be 3495.

Tiger I don’t know what the Y-SNP count is on the MyHeritage and FTDNA chips. Living DNA now use an Affymetrix chip: https://livingdna.com/blog/we-have-a-new-chip See this very informative blog post

Thank you, Debbie. Are there comparison numbers for Y SNPs in these tests? My guess is LivingDNA has more.

Hi Centropol I don’t think the problem of false positive matches will affect the so-called ethnicity reports as they are working out in a different way and are not reliant on detecting IBD

Both FTDNA and MyHeritage started out using the Illumina OmniExpress and changed over to the Illumina Global Screening Array in about 2018. There is very low overlap therefore between old and new

Mike, thank you for sharing this story of how persistence and investment paid off. Linda Horton

Hello Mike An excellent summation of excellent results; thank you. Not sure how busy Iain is at this time of year; but he wrote about Stochastic Variability in a post some time back.

Hello CB There has always been a significant difference in SNP tested men in the Public Haplotree compared with the Discover Haplotree Reports. That difference is now 11,281 more in Discover, but a

The public tree shows 4,474 for Z156 and the discover reports show 4,516. It seems like it is going to be a long slow process if there are 750,000 male FF testers.!!!!! Only 5 of my 629 M269? 25

Back in April of this year I posted this introduction to the group: "I'm new to this group (just got BigY results and I'm U106) and wondering about possible mutual benefits between the Tryon surname

I did the Genographic 2.0 test in 2016, and imported the results into FTDNA in the same year. Genographic reported my haplogroup as Z160, now dated 2170 BCE (95% confidence interval: 2816-1610 BCE).

In general one needn’t worry about FTDNA/MH transfers as FTDNA processed all of them and the SNP overlap is very high. Some people like their MH ethnic origins %, but many people would place them at

Hi, FTDNA Discover has just been updated with new data from FF/Y-SNP testers (7018 subclades, equivalent to the Y-DNA haplotree data from December 8, 2023). Attached is a link to a European map by

That is very interesting. If the rate of false positives "child-only matches" is so high then I also wonder how it affects the ethnic origin estimated in MH, although for my mother the estimate

MyHeritage have a database of 7.7 million whereas FTDNA’s Family Finder database is only about 1.5 million so you would expect many more matches at MyHeritage though I’m sure you’re right that

Thank you very much Debbie. That really clarifies a lot and explains why I have 2x more matches in MH compared to FTDNA, although MH is a bit more popular in Poland, I think, also because of the

Hello Centropol MyHeritage use a complicated process using imputation and stitching to compensate for the low overlap of markers on the different chips. The process is described in this blog post:
