主 题:Ancestry inference autosomal single‑nucleotide polymorphism Y‑chromosome
摘 要:The Y‑chromosome has been widely used in ancestry inference based on its region‑specific haplogroup ***,there is always a debate on how informative such a single marker is for inferring an individual’s genetic ***,we compared genetic ancestry inferences at continental level made by Y‑chromosomal haplogroups to those made by autosomal single‑nucleotide polymorphisms in 1230 samples of Affymetrix Human Origins *** highest ancestry proportions of a majority of individuals match the highest average continental‑ancestry proportions in haplogroups A,B,D,H,I,K,L,T,O,and *** high consistencies have not been observed in haplogroups E,C,G,J,N,Q,and R,but in some of their sublineages,such as E1a,E1b1a1,E1b1b1b1a,E2b1a,J1a2b,Q1a1a1,Q1a2a1a1,R1b1a2a1a,and *** the consistencies of Y‑chromosomal and autosomal continental ancestry vary among haplogroups,Y‑chromosome could provide valuable clues for individual’s continental ancestry.
