hi, here is an interesting GeneU tool which can show all Y haplogroup distribution in China and the most commonly used Chinese surnames of which Y haplogroups compose, and average ethnic group composition all over China.
This utility has been verified by WeGene and can be accessed on WeGene website and these gene data are all originally from wegene.com and can only be used for study without any commercial use. If anyone has suggestion about this, please contact me by Email.
