Are you also saying the others don't show as matches from the BigY testing but that they show as matches to each other? If so, STR testing of 67 or more markers should have already indicated that...

Yes it is a very big drawback apart from the fact that Y111 STR matches are normally from a more recent time frame than BigY matches. Since most people are more interested in a genealogical timeframe...

A threshold of 30 non-matching variants (SNPs) has been added to the matching algorithm. If you have more than that limit with anyone then they won't show as a BigY match. That means that all of your...

This is the main problem. BigY is still too expensive and still not popular enough for everyone to have someone that they share currently unnamed variants with allowing them to get a new designation...

There is a hold up in naming new SNPs and providing VCF files and BAM files due to a the hg38 upgrade taking too long. But you also have to take into consideration that L20 is just one relatively...

No is saying that the mutation rate is an exact constant. The estimates are just that because the mutation rate is an average and not a constant. The number of SNPs each person has since any of the...

It's not the clades that matter. It's the number of mutations each sample that matter. Of course, anything that is variable can have a much wider margin of error in smaller groups when applying an...
