A Question I've Always Had On The Races...

[OranKells]

Even in the real world, closely-related species (like the various big cats) can interbreed but the offspring are often infertile.

basically

lions + tiger = ligers
horses + donkey = mule/hinny
wolf + dog = wolfdog

most of these hybrids are pretty viable but also incapable of further reproducing. While any two races might be able to have a child, there could be some genetic health issues that come up. This along with whatever racial strife exists in the lore is why you generally wouldn't want to intermingle.

I shudder at the though of a lala-ronso.

I recall reading somewhere that it was stated in an interview during HW times that all the playable races (at the time) can successfully interbreed and have viable offspring, just that it's very rare because of social taboo and because SE don't wanna make unique models. The rest seems to be headcanon or hearsay that everybody treats as canon (such as the resulting child being mostly the mother's race plus some minor trait of the father, likely due to Hilda who has a midlander hyur's body and animations like her mother but her elezen father's pointy ears).

I shudder at the though of a lala-ronso.

Just assume the lala is the father.

An interesting way of thinking but unless we have proof from the game, this is merely a conjecture.
We're applying real life biology to a fantasy world without evidence from the game itself.

okay the real reason is that devs do not want to make the 40+ new character models would be needed to make each hybrid. but if you're looking for a lore reason its a combination of racial/cultural tensions and biology 101
