1 in 200 men direct descendants of Genghis Khan | Gene Expression | Discover Magazine: As Y chromosomes are only passed from father to son, that would mean that the Y is a record of one’s patrilineage. Genghis Khan died ~750 years ago, so assuming 25 years per generation, you get about 30 men between the present and that period. In more quantitative terms, ~10% of the men who reside within the borders of the Mongol Empire as it was at the death of Genghis Khan may carry his Y chromosome, and so ~0.5% of men in the world, about 16 million individuals alive today, do so.
