title: [Y chromosome variations and hyplogroups from 15 biallelic markers in six Chinese populations].
abstract: By using 15 biallelic markers, 342 male individuals from six populations in China were genotyped with ASPCR (allele specific PCR). The 15 biallelic markers included M1 (YAP), M15 (9 bp insertion), M89 (C-->T), M9 (C-->G), M119 (A-->C), M50 (T-->C), M110 (T-->C), M103 (C-->T), M95 (C-->T), M88 (A-->G), M111 (2-bp deletion), M45 (G-->A), M122 (T-->C), M7 (C-->G) and M134 (1 bp deletion). The distribution of variation frequencies of 15 biallelic markers in six populations showed that with the extremely high frequencies of M9G (96.20% & 96.43%) and Han nationality displayed higher diversity than the four minority populations. It's noteworthy that M95T (82.14%) in Sichuan Han and M45A (18.57%) in Hui gave prominace to the two populations. The six populations displayed 34 (Fujian Han), 21 (Sichuan Han), 14 (Mongol), 26 (Hui), 10 (Xibo) and 8 (Hezhe) haplogroups respectively with 2, 1, 2, 1, 2 and 2 prominent haplogroups among them. Furthermore, the haplogroup analysis revealed that one predominant haplogroup was shared in the four minority populations and even two predominant haplogroups were shared in Mongol, Hezhe and Xibo. Unlike Han populations, the minority populations showed strikingly different haplogroups which were close to the ancestral pattern. However, the two Han populations exhibited divergence between them with the distinct frequencies of M89T and M95T. With the comparison of the number of people sharing the common haplogroups between any two of the four minority populations, relative genetic distance among them was deduced.
