    It largely depends on how prevalent it is socially.

    In societies where first cousin reproduction isn’t common, the increased risk of birth defects is about the same as a pregnancy where the mother is in her 40s.

    In societies where it is common, the rates can go up sharply though when it compounds across generations.

      Good point. Who cares about the lower rates, honestly? Its not like we’re the ones that have to live with the defect lol, keep blasting homies
