1、Y染色体DNA单倍群介绍1、Y-DNA单倍群人类Y染色体DNA单倍群由非重组DNA的Y染色体突变进行定义。这种由许多人共享的突变称为单核苷酸多态 性(SNP)。人类Y染色体每一代大约积累两次突变。Y-DNA单倍群的分支结构组成一个Y染色体进化树,有数 百甚至数千的突变由这些不同的单倍群共享。Y染色体的最近的共同祖先(most ...

Recent male-mediated gene flow over a linguistic barrier in Iberia, suggested by analysis of a Y-chromosomal DNA polymorphism. We have examined the worldwide distribution of a Y-chromosomal base-substitution polymorphism, the T/C transition at SRY-2627, where the T allele defines h... ME Hurl...

参见维基:《File talk:World Map of Y-DNA Haplogroups.png》:“Replace Turkmen R1b with Q-m25”和“Why Q1a1b was mislabeled as R1b1 (both are defined by m25”。 有人可能说为什么Y-Q在今天中东仍然低频,其实这个情况与华夏-汉在东方遇到的情况一样,古埃及新王国时代,由于不断与入侵的利比亚人、...
在中西伯利亚南部的阿尔泰地区一具死于24,000年前的男孩遗体被发现,之后在DNA检测中鉴别出单倍型R*。这个男孩属于一个在旧石器时代游猎在从欧洲到西伯利亚的猛犸猎人部落。与之相对应的常染色体被发现散布于现代欧洲到南西伯利亚的远古时代遗址中,时至今日,此单倍型已经繁衍成显赫的两个大支——R1b单倍型和R1a单倍型,...

(2015) tested the Y-DNA of 13 Early Neolithic farmers from the Barcın site (6500-6200 BCE) in north-western Anatolia, and 8 of them belonged to haplogroup G2a (subclades G2a2a-PF3146, G2a2a1b-L91, G2a2a1b1-PF3247, G2a2b-L30, G2a2b2a-P303, G2a2b2a1c-CTS342). The other ...
