What happens is that (I'm not sure if I actually get the facts right as to which has which in terms of male/female.. but the concept is right) When you have male Tiger/Female Tiger.. one of them..let's say the female tiger has the growth cut off gene.
Same with lions. But it's the opposite. So... the male Lion would have that gene.

So.. you take the Male tiger.. and a female lion.. and it whacks out that gene... allowing the liger to grow like woha!

but all (most) hybrid animals are sterile.




The more you know.

 

I always thought that by definition all hybrids had to be sterile. I thought that the definition of a species was a population that could breed and produce fertile offspring. Although I think there are hybrids that can breed but then their offspring are infertile. That way the other species genes never enter the gene pool. Someone might have to correct me on this.

 

That's what I thought. :dunno:

 

They are... but.. as with most cases.. there is that small percent freak chance that can defy nature.


(That's why I threw in that "most". I personaly don't know of any instances)
