Why are female ligers/tigons fertile

Personally I saw him on channel 4, and yeah thats what i ment, he must have been a cross between a man/monkey man/ape. Thats so disgusting though, but he was a amazement, people thought he was a missing link at first, but then they concluded some-one actually "did it" with a primate. And he was the result.

I don't know WHAT you were watching (and frankly I don't wanna know) but that isn't what they concluded.

They did a blood test on him and found that he was in fact pure chimp, and the reason he was attracted to human women is because he had never been in a chimpanzee social group, only humans. He adapted accordingly.

He was all chimp, as this link shows.

Male ligers are sterile, but female ligers are fertile and can be bred to tigers (resulting in ti-ligers) or to lions (resulting in li-ligers). Ti-ligers are more tiger-like, having a greater percentage of tiger genes. Li-ligers are more lion-like, having a greater percentage of lion genes. Neither are common. The fertility of hybrid big cat females is well-documented across a number of different hybrids. This is in accordance with Haldane's rule: in hybrids of animals whose gender is determined by sex chromosomes, the heterogametic sex (the one with two different sex chromosomes e.g. X and Y) is either absent, rare or sterile.

Little bit of friendly help to confusion about the REAL topic, maybe?

and to the monkey thing.....apes/monkeys are not anywhere near genetically compatible with humans......number of chromosomes doesnt match up.....if they did....or were close enough....then we would see a whole lot of monkey-people in africa, where some cultures still practice sex with primates
