Anyone here ever heard of this? I work in the health insurance field and we recently had a claim where a white female had paternal twins, one black, one white. It is causing all kinds of issues. Its rare when it happens, but after studying up on it, it happens more often than not, just hard to prove that 2 or more men are involved. Happens with cats all the time! I've seen a female cat have 5-6 kittens, and some long hair, some short hair, etc. Heteropaternal superfecundation occurs when a woman releases 2 or more eggs in her cycle, and those eggs are fertilized by 2 or more sperm from 2 or more sexual intercourses. First known, proven case of this happened back in the mid-1800's when a white woman had 2 babies, one black, and one white. There have even been cases of triplets where 3 eggs were fertilized by 3 sperm by 3 different men. Imagine an oxtimom situation, where the female releases 8 eggs and has gangbang sex with a lot of men ... the possibility of her having 8 babies at the same time, all by different fathers. Weird, huh? Gets you to thinking ... wow!
