Born sterile

*ahem* I'm not toking abt anyone in particular... rather, I'm talking about animals!

Do you know which animals are sterile at birth? i.e the animal cannot give birth to itself.

I'm not talking about individual animals, i'm talking about an entire species.

Ah you argue that it is impossible? afterall, if the species is born sterile, what gave birth to it since that species cant produce itself? Shouldn't it die out?


Hah. But you are wrong! There really are animals born sterile and yet they still can exist despite that seemingly problematic situation they are in. Can you think of any?

nope?

hehehe. Read on read on! *grins*


Well, there are actually many animals that are sterile at birth! Two examples would be mules and ligers.

A Mule is a cross between horses and donkeys while ligers is a cross between a lion and a tiger.

Most hybrids are born sterile with the very few and very rare exceptions. These animals cannot breed on their own to produce their own young. However, they can still exist because they are the offsprings of two non-sterile but different species.

Aint they pretty? Wow if you keep them as pets you dun ever hafta worry abt them humping the pets next door! oops. =p
