Cousin marriages - ghar ki murghi??

@fasaadi

not necessarily…the example thats coming to my mind relates to specific groups e.g. within Memons or Punjabis where marrying outside that group of particular ethnicity from a particular city is taboo. In that case, you might not be marrying a direct cousin, but lets say all Jetpur Memons marry only other Memons who also came from Jetpur. The probability of you carrying the same genes or similar traits are much higher. But in general, I see your point…my main point was that disease is not the major risk here because most people wouldnt carry these rare, dangerous hereditary diseases…but infertility is an almost immediate and absolute risk.

Is this for one generation of cousin marriage or after many? And what is the risk compared to unrelated couples?

I agree with you though.. I have said many times that marrying within the same group generation after generation is just asking for problems.
