Re: Hg38 to T2T upgrate


 

There are no more matches on my kit at YFull probably because the terminal snp is at Y7378 (above what FTdna has as the final), but it's interesting to see the number of snps that are now 'positive' which previously were marked as 'no call' or 'negative'.

Hi Ciar¨¢n
Before the upgrade I had two SNP matches at the level Y128031. With one, a BigY500, I had 34 shared SNPs and 20 assumed shared SNPs. With the other, a T2T Nebula Genomics test I had 43 shared SNPs and 5 assumed shared SNPs. After the T2T upgrade with the Big Y500 match I? had 29 shared SNPs and 18 assumed shared SNPs. With the Nebula Genomics test I had 51 shared SNPs and 3 assumed shared SNPs. It would seem that the T2T test brings more certainty to matches, with fewer assumed matches. YFull are revising age estimates.
Because the Nebula Genomics tester only recently uploaded to YFull, I expect the next version of the YTree will show some more branching for me and my two SNP matches.?
