主题:浪友都是东北亚洼地北支吗?
回复:这种分类跟ANA(Ancient Northeast Asian), ANEA(Ancient Northern East Asian), ASEA(Ancient Southern East Asi...
这不是分类,是蒙古相关人种免疫球蛋白遗传标记(Gm),最早来亚洲的是ag/axg,之后ab3st和afb1b3,这些都是几万年前的事了,你说的ANA/ANEA/ASEA这些都是针对一两万年前生活在亚洲某些地区的人进行分类,所以跟现代人没区别,就是几种Gm配比不同,参照我前面写的,ag/axg打底,越北则青虫ab3st越多而马来afb1b3越少。
Since the discovery of Gm ab3st haplotype which characterizes Mongoloid populations in 1966, the distribution of the genetic markers of immunoglobulins (Gm) among the Mongoloid populations scattered from Southeast Asia through East Asia to South America has been investigated and concluded as follows: 1) Mongoloid populations characterized by the four Gm haplotypes, ag, axg, ab3st and afb 1b3 are divided into two groups on the basis of analysis of genetic distances based on the Gm haplotype frequencies: one is a southern group characterized by a remarkably high frequency of Gm afb 1b3 and a low frequency of Gm ag and the other is a northern group characterized by a high frequency of Gm a and an extremely low frequency of Gm afb 1b3. 2) Populations in China, mainly Han including minority nationalities, show remarkable heterogeneities from north to south, in sharp contrast to Korean and Japanese populations showing homogeneities, respectively. The center of dispersion of the Gm afb 1b3 characterizing southern Mongoloids must exist in Guangxi and Yunnan area in the southwest China. 3) The Gm ab3st gene found in the highest incidence among the north Baikal Buriats flows in all directions. The gene, however, shows precipitous drop which occur from mainland China to Southeast Asia and from North to South-America, although the Gm ab3st gene is still found in high incidences among Eskimos, Yakuts, Tibetans, Olunchuns, Koreans, Japanese and Ainus. On the other hand, the gene is introduced into Huis, Uighurs, Indians, Iranians and far Hungarians.(ABSTRACT TRUNCATED AT 250 WORDS)
