Wait… how do Punjabis have Asian genes? I mean what do you mean with the ‘Tibetan region’ ?
They have Mongoloid genes. Look at their eyes. It is quite common to see Punjabis with Mongoloid eyes to some degree or another. There are quite a few Mongoloid residing to the north of the Punjabis. I assume the Punjabis must have bred in with them somehow. The Mongoloid genes in Punjabis are 14%. A bit to the north of the Punjab is Tibet. I assume this is where the Mongoloid genes must have come from or thereabouts.
