Are they sterile? If not, you should cross one back with a lion and work on a huge super cat.

despite the repeated assertions that they are sterile, the answer is more complex.

the male hybrid offspring ligers are generally sterile the female ligers are fertile.

so for example a tiliger is the offspring of a male tiger and a female liger.

it seems most of the great cats have some limited interbreeding, so tigers, lions, jaguars, leopards, and snow leopards.

Iirc cheetahs bottlenecked so hard at some point their diversity is terrifyingly small.

Ah, just like humans.

Worse. They can pretty much take an organ donation from any other cheetah worldwide with no rejection or special considerations

That sounds amazing at first, but then the turntables turn

Is a male tiliger sterile? Would it be possible to breed a stable crossbreed through selective breeding that produces non-sterile males?

if I recall male sterility isn't 100% but I haven't looked at any of the information in a long time.

This sounds like the mad scientist idea from a B horror / apocalypse film.

This sounds like some human transmutation shit. Y'all gone fuck around and break the law of equivalent exchange

Unsure about ligers, but some female tygons (reverse parentage from ligers) have in fact been fertile.

Not always. Though near enough to 100% that it counts as such I suppose.

not for panthera.

the male ligers are sterile, the females are fertile

Like most of biology. An exception for e very rule. Life, uh, finds a way.

Not true. Sometimes the hybrids do just fine, like in the case of tilapia, or apple trees.

It can also be highly sex-dependent. For example, you can cross a domestic cattle bull with a bison cow, and the female offspring will generally be fertile, and the male offspring generally will not be.

However, those hybrid cows can reproduce with male bison, and now almost every bison herd in North America has some fraction of domestic cattle genes in it.

Yak bulls can produce fully fertile offspring of both sexes with Bison cows, but not the other way around.

Your example of Apple trees is wrong. Apple trees are spliced to get the strain you want. You could have two apple trees of the same type and the the offspring would be a completely different apple.

You’re responding to something I didn’t say. I didn’t say anything about fruit variety propagation. Malus sylvestris crosses with M. sieversii, M. coronaria and a bunch of other species just fine, producing fecund offspring.

Whether you get a palatable apple from the cross is an unrelated question.

No. Though that is an easy rule that works a lot of the time, it’s not a hard rule. Canids, for example, are very good at interspecies breeding and produce viable, non-sterile offspring.

If that were true humans wouldn't exist. Most humans have DNA from Cross breeding with other species of human like Neanderthal and Denosovens
