this is so wrong, the chances of any child being born with no problems is minute. and legalising it is paramount to encouraging it.
come on Switzerland, get your crap together
Actually I believe the chance of defects only goes up a tiny amount. Google the statistics if you don't believe me.
The chances of defects only really go up with each generation.
Two siblings having a kid together, the chances are pretty small, but if they have two kids and then those two kids have a kid, the chances go up, and so on.
It works like this: everyone has certain defects in their genes, though in most cases they're recessive, so they don't show. Not everyone has the same defects, so those defects tend to stay recessive with non-related couples.
Mate two people with the same recessive defects, and the chances of any of those defects appearing go up. Whether they're related or not. It's just that related couples have ALL the same defects in their genes, so the odds of any ONE of those defects appearing will go up.
So while the chances of relatives having a flipper baby are technically higher, they're still not very high in the first generation, and it's only gonna happen if you have the flipper baby gene already.
I'm trying to come up with a metaphor involving bingo cards, but it's not completely accurate.
To put it another way, if you created a family with perfect genes (no recessive defects), they could mate with each other nonstop without end and never have a defect baby. Not sure this is technically possible though.
