Northern Mongoloid

From Wikipedia, the free encyclopedia

A trait Northern Mongoloids with considerable Caucasian Admixture is blue eyes but it is very rare

Northern Mongoloid populations are a subgroup of Mongoloid populations, distinguished by older criteria like appearance and craniology, or dental patterns.

In Cavalli-Sforza's genetic clustering work (1988) South Chinese join Southeast Asians in genetic clustering while the North Chinese genetically cluster with Koreans, Japanese, Ainu, Bhutanese and Tibetans. Xiao and Cavalli-Sforza (2000) find the boundary between Northern and Southern Mongoloids to approximate the Yangtze River, and suggest that their ancestors arrived from Africa via separate routes. Principal component analysis of gene frequencies of Chinese populations

Other scientists have suggested that the finding of sharp genetic differences between North and South China is an artifact of using an insufficient number of samples. However, Xiao and Cavalli-Sforza (2000) used a larger number of samples than previous studies.
