    Genes mutate.

    If you have one copy of a mutated gene, it could be bad. However, one mutated gene is usually recessive or will be co-dominant with the other gene so it isn’t that bad. If you have two copies of that gene, it can be a lot worse.

    Two close family members are more likely to have the same mutated gene, so the odds of getting that same mutated gene twice are a lot higher.
