It’s more useful to list what percent of genes you should share
That and the likelihood of common negative recessive genes are really the most important thing about cousin fucking.
I’m not a geneticist, but you really have to think about the birthday paradox here. You have how many genes, and how many are recessive? The odds of a collision are probably way more than you’d think.
Anyways, please don’t reproduce with your cousins, until they’re so distant you no longer have a vocabulary to describe it.
Iirc, two random cousins fucking has a small but non-negligible chance of creating a genetic issue - something like 1% chance. And at second cousins, your odds have essentially dropped to background levels. The problem arises when everyone in your family only fucks their cousins.
Not every recessive gene is a death sentence.
Incest is Wincest
Well, if you’re rich, you like easy stuff. And your cousins are right there! You have them within easy reach at family gatherings! You can keep your precious money within the family! You can groom them from a very early age if they’re younger than you!
