>>212523172>If it is simply relying on the marriage certificates, how does it specifically correlate with genetics?officially recorded ancestry from church records correlate extremely highly with actual ancestry (and hence genetics) because genetic cuckolding only happens in a small minority of cases and would only introduce a little bit of noise. The pattern is so strong and the model fit is so good that even even with this little bit of noise very strong evidence for the genetic model is found due to the genetic model making such accurate predictions about the data.

the model predicts that more genetically similar relations are more closely correlated in terms of their socioeconoomic success, not that more genetically similar relations are more socioeconomically successful.
>What about genetic abnormalities? What's the "distance" with that?distance basically refers to how much blood you share. a child receive half its; genes from it's mother and half from it's father. This is also true for that child's child, so a child receives on average 1/4 of it's genes from each of its 4 grandparents.
So a child is twice as distant from one of its grand parents as from one of its parents.
This is the basic idea but it is made more complicated due to assortative mating, which the paper explains
so genetic abnormalities don't impact how distant two relatives are
