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?

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.?

謝謝。其實我知道亞洲人的樣本和歐美人的樣本相比要少很多。這個跟我們的人口完全不成比例，不對稱。你覺得現代漢族的血統還純正嗎？還有人說客家人是最純正的漢族，不知這個說法是否正確。你在我另一個帖子里提到北方漢族和南方漢族都受到了來自南俄草原民族的影響，北方漢族比較多。請問你這指的是哪些地方和哪些人群？

我希望WeGene能夠成為專門為中國人服務的基因檢測，彌補我們在這個方面的缺陷。你們什么時候會再次更新祖先分析？會增加哪些新的categories?

我爸爸也進行了23andMe的檢測，現在他剛拿到他的初步結果。等他的Ancestry Composition出來以后我會讓我的結果和他的進行phasing, 不知道到時候能不能重新上傳我經過phasing的數據。

謝謝！

最后一個問題，你從我的結果 (WeGene和23andMe) 能做出什么判斷？
