    Bengali,

    Just to reiterate MDL's point, there is not much BMAC ancestry for most / any Bengalis.

    With the simple model that he posted above, I have the following results:



    Once you account for excess steppe to what Telegu average has, you can see that any BMAC effectively disappears apart from some individuals with this:



    The fits aren't brilliant for my family / region (I don't think Burmese is always a good proxy for the TB/EA in us) but it paints the picture. For the ethnogenesis of Bangladeshis, BMAC wasn't significant.
