>>508429490 (OP)Can't remember where I learned this, but I remember reading once that westermark effect ceases to apply when in high stress, perceived life or death scenarios. In other words, incest is more "normal" to understand for an individual when there is large amounts of poverty and life threatening danger, the idea is that you reproduce immediately anyway no matter what to continue on your genetic code. I believe your second cousin is when genetic data is distant enough to not pose any risks of recessive genes becoming more pronounced from incest.
