The frequecy of three major branches of O3 in Chinese provinces(not include the ethnic minority),draw by Dr Shi Yan,in some provinces,the sample number is too small,so Heilongjiang,Jilin,liaoning and Inner Mongolia into one(Thus Northeast).Xinjiang,Gansu,Qinghai,Shaanxi and Shanxi into one(Thus Northwest).
http://www.ranhaer.com/thread-16435-1-1.htmlM134XM117,it seems this branch is most common in northwest China,then northeast China,very low in southern China.Accord to Dr Shi Yan,all their M134XM117 samples belong to a single SNP,this branch is smallest of three major branches of O3,but maybe younger
M117,also common in northwest China,but also common in southern China like Guangdong and Fujian
002611,common in east China,highest in Hunan province
