Why is Asian ancestry understudied compared to European ancestry?

Western personal genomics services such as 23andMe, Family Tree DNA, and AncestryDNA give not-so-great results for individuals of Asian descent. I've noticed that overall, East Asian ancestry has been studied much less compared to European ancestry. Why is this? Could it be the lack of reference samples, or simply because not many people in Asia know about genealogical DNA testing?

I'm happy WeGene is the first company that focuses on testing Chinese / East Asians. Will we get out first beta results for ancestry composition in a few (2-3?) weeks?

谢谢。其实我知道亚洲人的样本和欧美人的样本相比要少很多。这个跟我们的人口完全不成比例，不对称。你觉得现代汉族的血统还纯正吗？还有人说客家人是最纯正的汉族，不知这个说法是否正确。你在我另一个帖子里提到北方汉族和南方汉族都受到了来自南俄草原民族的影响，北方汉族比较多。请问你这指的是哪些地方和哪些人群？

我希望WeGene能够成为专门为中国人服务的基因检测，弥补我们在这个方面的缺陷。你们什么时候会再次更新祖先分析？会增加哪些新的categories?

我爸爸也进行了23andMe的检测，现在他刚拿到他的初步结果。等他的Ancestry Composition出来以后我会让我的结果和他的进行phasing, 不知道到时候能不能重新上传我经过phasing的数据。

谢谢！

最后一个问题，你从我的结果 (WeGene和23andMe) 能做出什么判断？

First of all, there are actually no available reference data for ancestry comparison. 1000 genome, HGDP or other international projects have only included very few Chinese populations. Researchers in China would very much like to sequence individuals for medical purpose, and they usually only report what they find but seldom publish raw genetic data. Chinese populations, not like Americans or Europeans, are actually very “pure”, especially Han Chinese. There are probably no such strong desires for ordinary people to trace their ancestry.
