But anyway I have not posted the other 2 graph regarding DNA that I am posting now and that is indicating there is presence of DNA of middle east and central asian people.
The graphs are as below:

It can be seen from the graph that U2i, U2b, U2c, M18, U7 (which has a very strong presence in central Asia and middle east), R5, R6 DNA are also present in Bangladesh which has a very low presence in South India.
But point to be noted it has been said that M2 has a presence in Bangladesh up to 83% of the people.
From the above data it can be said that most of the urban and upper society people are from Indo-ariyan group but most of the lower caste / class group of people are dravidian or mix up of Dravidian and Arian group.
It also align with the story that majority of the early muslims were the convert from lower caste people and most of them are residing in Bangladesh and can be found in villages or the poorer class people.This also tells the story why M2 is not present in the Brahmins and Kshatriyas people of even west Bengal and other northern India as majority of these people were treated as lower class by hindu upper class.
If anyone look at the villages or other places it can be seen that there are presence of many dark skinned people just like the south Indians. They may be the byproduct of Dravidian group. Brown people are the intermix and white are of arian origin.
Any correction or suggestion will be highly appreciated.
