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.
Since 2003 there have been other cases of “super-Y” lineages.
In 2003 a groundbreaking historical genetics paper reported results which indicated that a substantial proportion of men in the world are direct line descendants of Genghis Khan.
By direct line, I mean that they carry Y chromosomes which seem to have come down from an individual who lived approximately 1,000 years ago.
The pattern of variation within the lineage suggested that it originated in Mongolia ∼1,000 years ago.
For example the Manchu lineage and the Uí Néill lineage.The existence of these Y chromosomal lineages, which have burst upon the genetic landscape like explosive stars sweeping aside all other variation before them, indicates a periodic it “winner-take-all” dynamic in human genetics more reminiscent of hyper-polygynous mammals such as elephant seals.
