I wonder what the degree of relatedness (assuming inbreeding) these descendants actually have with Genghis Khan. We know that family trees break down into direct acyclic graphs over the longer term.
Note that the title assumes just patrilinear descent, so any man that may have had only daughters will not pass on the Y chromosome, though he will still have a non-patrilinear lineage (carried by both sons and daughters).
BTW, what are the main structural differences between strictly male and strictly female lineages?
- Someone 15y agoThe obvious one is a difference in branching factor. Women can have ten children, and I would expect many more men than women die childless (not only because more than half of all newborns are male)
- jodrellblank 15y agoI remember reading a long article/blog entry once, and it claimed that we living humans are descended from 80% of all the women who ever lived but only 40% of all the men. Haven't been able to find it again, though.
