Hey guys it turns out that only male Tiglons are sterile all the time: the females actually aren't, and can mate with lions and tigers and so forth.

I don't really know how that affects the discussion, but doesn't that make lions and tigers genetically compatible?

That is wierd. Can you link me, or tell me where you read/heard that? Maybe it has something to do with mtDNA and Y-DNA. Y-DNA being is transfered Paternally, and mtDNA is tranferred Maternally. I'm thinking maybe a closer Maternal ancestor?
