Researchers at Chinaโs top forensic academy in Beijing say they have found genetic differences between three ethnic groups in East Asia โ northern Chinese, Korean and Japanese.
These differences are coded in less than 50 variations across the sequence of the human genome, and the scientists said these genetic codes could be used by police to trace someoneโs origin as a way to help identify a body.

Genetic variations among people from different ethnic groups have generally been found to be negligible, although they may look different. And people from northern China, Japan and the Korean peninsula have a close genetic link.
โThe genetic relationship between the Han Chinese and Koreans or Japanese is closer than the relationship between the Han and ethnic minorities in China,โ [forensic scientist Li Caixia] said in the paper.

โThese tiny differences must not be used for discrimination, nationalism, as biological weapons or for other purposes, to sow more divide or conflict in this region,โ [an anonymous scientist at the China National Centre for Bioinformation] added.
