Here is which ethnic group composes 45% of the Han DNA (chinese)

[tita]

Following K12B, Hans have 45% DNA in common with the Paniya people https://en.wikipedia.org/wiki/Paniya_people
How is it even possible ?

What happens when you mix East Asians with Oceanians/South Asians. Like Southeast Asians, just with a lot more Oceanian.

And it's the other way, it's not the Han who are 45% Paniya, it's the Paniyas who are 45% of something East Asian/SEA.
