Genetic affinities of the central Indian tribal populations.
<h4>Background</h4>The central Indian state Madhya Pradesh is often called as 'heart of India' and has always been an important region functioning as a trinexus belt for three major language families (Indo-European, Dravidian and Austroasiatic). There are less detailed genetic...
