Is that really a health concern though? Single generation shouldn't have risks higher than some already at risk people have no matter who they partner with.

- reitanqild 7y agoWhat I've learned is that there's significant risk even for cousins who have children together, so even more for half siblings.
- pgeorgi 7y ago... if the cousins' parents and grandparents are similarly closely related to each other, yes. Otherwise probably not.
- jacobolus 7y agoMy understanding is that 1 generation of first-cousin marriage is very low risk. The problem comes when you have many generations of family marriages in a row. The Catholic church tried to make cousin marriages taboo as a way to break up clans and solidify church power.
- blueblimp 7y agoYou're right. It's weird that people are rushing in here to defend inbreeding. What people might not realize is even when there's not a specific disease caused by the inbreeding, there is still an overall negative effect on health, "inbreeding depression". Here is a paper that estimates the effect in humans: https://www.ncbi.nlm.nih.gov/pubmed/26131930 https://www.ncbi.nlm.nih.gov/pubmed/26131930.
