Advocating haplogroups to ancient ethnic groups

[we92]

Is it possible that haplogroups are the markers of some ethnic groups that lived in the past but became assimilated by time?

[zebruh]

usually no. But more recent mutations of sub groups possibly.

I don’t get what you’re asking but I’ll attempt to answer it. Haplogroups are markers of things that happened very long ago. For example if a Chinese person moved to Europe and mixed with the locals after 5-7 generations their kids will carry an Asian haplogroup and almost none of the autosomal dna and their kids will have none or very little Asian features in them. So their kids then claiming to be 50% descendants of ancient Chinese for example based on their Asian haplogroup wouldn’t make sense given them autosomal dna.
