    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.
