I propose to delete all the genetics stuff from the article for multiple reasons:

• Not one indologist cites genetics to discuss Aryan migration. Indologists use linguistics, archaeology etc.
• The genetics info is mostly WP:OR. We discussed this stuff previously HERE. Particularly note the comments of admin Dougweller. WP: OR states "you must be able to cite reliable, published sources that are directly related to the topic of the article, and directly support the material being presented." A lot of these genetics studies don't even mention Aryan migration at all.
• Joshua Jonathan, who displays complete WP:OWNERSHIP of this page for years, is WP:CHERRYPICKING to the extreme. I will provide one illustrative example. He cites Sahoo 2006 repeatedly without presenting the central point, which is the following:

The Y-chromosomal data consistently suggest a largely South Asian origin for Indian caste communities and therefore argue against any major influx, from regions north and west of India, of people associated either with the development of agriculture or the spread of the Indo-Aryan language family

• Delete all genetics stuff-Per above.
