Hairless rat litter

[Highline Reptiles South]

I don't remember who the daddy was but this was an interesting rat litter. I've always understood that they are double rex "hairless" as they came from two "normal" looking parents. I've had a couple of others like this that were almost completely hairless as adults withe curly whiskers.

What are they exactly?



Normal


Hairless



Bunch of "hairless"

looks like a trio that I have, all came from het dumbo to dumbo pairing. I was told it's possibly a recessive hairless trait.

Got a pair of normal looking offspring from one of them to an albino that I'm gonna breed together, and a pair of the hairless ones that I'm trying to breed without my luck.

If they came from two normal parents (neither are rex), and there are no rexes in the litter, then they are hairless.

i haven't been able to breed two hairless. I have a suspicion hairless = sterile but i'm still trying to prove it.

When they are born like this they end up being almost completely hairless when they get larger.

Not sure what matchup produced these but they are really cool. You can see they are all dumbo as well.

Hairless = recessive

Rex = co-dominant = 50% rex 50% normal
Rex x Rex = Patchwork Hairless = Dominant

[Rhasputin]

Hairless = recessive

Rex = co-dominant = 50% rex 50% normal
Rex x Rex = Patchwork Hairless = Dominant

Rex x Rex = patchwork hairless (double rex) = dominant? That doesn't make sense.
Rex is always co-dominant, no matter what the circumstance.
