So, I assume that if you put 100 people on a spaceship and sent them to wherever, they’d get very inbred in a few generations. How many people would you need for this to not happen, accounting for the fact that there will eventually be people who are infertile or die before having children?
similar DNA is bad actually, the whole point of sexual reproduction is to increase diversity to make the population as robust as possible. If you have a ship full of clones all it takes is one virus/bacteria/fungus mutating in just the wrong way and everyone will get infected.
Like, this is why we got a new type of banana some decades ago, it’s all giant monocultures which is hilariously vulnerable to disease.
I don’t think you realize the genetic diversity even among a close family…
But I have no idea why you’re talking about clones.
Kind of like if I said billionaires shouldn’t exist and you lept to saying that means I want money to not exist anymore
