Where Does Inbreeding Come from?

Inbreeding can lead to higher frequencies of genetic defects. Inbreeding occurs when the alleles at a gene site are identical by descent. This can occur when a common ancestor appears on both the maternal and paternal side of the pedigree.

Where did inbreeding originate?

We all started out in Africa when, around 60,000 years ago, small groups left to settle Asia and Europe. These groups were small enough that there had to be inbreeding at first. Of course, a small population isn't the only reason for inbreeding.

What country is the most inbred?

Data on inbreeding in several contemporary human populations are compared, showing the highest local rates of inbreeding to be in Brazil, Japan, India, and Israel.
