While it's possible for a leo and AFT to mate - as in go through the whole mating ritual, if your AFT had any fertile eggs, they were from a previous breeding with another AFT - the previous owner apparently failed to mention it to you.
Any eggs resulting from a leo\aft mating will be infertile.
Why?
Because they're two different species. "Species" is, loosely, a group of similar beings that can successfully interbreed - and do so naturally in the wild.
I add that last tidbit because yes - there have been other animals that resulted from an interspecies breeding. For example, the mule comes from the breeding of a horse to a donkey. However, because the parents are 2 different species, their chromosomes don't quite match up - the mule has an uneven number of chromosomes, making it impossible for it to breed.
They've also bred together lions and tigers - the liger. There is some question as to the result's fertility. I'm not as certain on that.. I do know, however, that that crossbreeding was ONLY made possible by the intervention of man. Number 1, they wouldn't have mated in the wild... NUmber 2, Man had to a bit of messing with the genes to get an actual baby.
HOWEVER, From everything that I have read & studied, it is genetically impossible for the breeding of a leo to an AFT to result in any fertile eggs. Their chromosomal make-up simply does not match up enough or correctly. It would take a scientist in a lab with tons of technology to achieve that one. That's like crossing a human with our closest genetic relative - the chimpanzee. If you wanted any results out of that mix, it'll only come from a lab. Not naturally. Our genetic make-up simply does not match up enough.
So your AFT that bred to your leo & then had gravid eggs.. She had to have been introduced to a male AFT before that - otherwise, those eggs would've been infertile.
