Wouldn't your above statement that China's population is a single base invalidate the OT's statement that China was more open to immigration?
Reading that link and following up on ASI, it looks like this is a truly ancient population set, ie: 3rd oldest after the first or second wave of migration out of Africa and past the Middle East. So it is interesting that this population set merged with numerous other population sets to form all the variation we see in South and South East Asia.
Yes, but that's less a function of openness to immigration than the enormous number of native Chinese. The development of rice farming lead to a massive demographic expansion in a very short period of time. It's mostly founder effects.
> Take for example, their Southern neighbour, India, I predict you see far more genetic variation.
You will, but that's more because the Indian population structure is I think, about 2,000 years younger. China's population has more or less one base. Modern Indians (subcontinent, not Republic) are a mix of Ancestral North Indian and Ancestral South Indian.
