Double Rex aka Patchwork Genetics

Ok. My Dumbo had a litter Xmas day. 9 gorgeous little pups. The dad is a Double Rex (always has hair on his face-sometimes more. Sometimes less. He also has very sparse hair in patches over his body, but looks hairless at a glance). Anyway, 3 of the pups have straight black fur and whiskers. 6 of them have curly whiskers and a very thin coat. I think these would be single Rex? Or am I mistaken?

Forgot to add: Mom is beige with ruby eyes. Supposedly no hidden genes. Just a Dumbo.

i think the rexXrex makes a few double rexes, few normals, few rexes. double rex bred to normal makes a few rexes and normals??? i dont know really i havent got my double rex male to breed yet (hes gay) but i have had a rex breed some normals and some other rexes and got rex babbies. one thing i did notice is some turned out to be rexes alot later than others in the same litter... id say 2 weeks till they turned out to be rex.
just for kicks here is a naked one i have

I have had double rex breed to a normal and throw entire litters of double rexes... I expected to get rexes (always been shady on rex genetics).

But have to say that double rexes are one of my favorite rats. I have 3 girls that are all naked bodied with fuzzy faces. They look like convicts. :D

Are you sure that normal wasn't a low quality rex? I've run in to that a couple times with our rats. Just a few weeks ago I got a litter with all rexes in it from a non-rex male bred to what I thought was a non-rex female. After digging through the records, it turned out she was a rex, we had just forgotten. :P A lot of times female rexes will lose most of their curliness as they get older.

What a cutie! I love these guys.

So far, looks like 3 Standard coats and 6 Double Rexes. One even has the same exact pattern as the sire's (convict beard). The rest just look mangy...lol.

Well, fairly new I must admit. From what I've read (& was told by one local breeder), Patchworks are Double Rexes. Not true hairless. Hair is just apparently very thin and breaks off (?). And it seems to be a Dominant gene (not recessive at least). The other info I've come across is that they do not seem to have the same health issues that some hairless rats have.

But I am definitely hoping to learn more!
