Chimeric Rat? Split face coloring.

He is from a blue x hooded breeding

He is visually a broken hooded and his face is two different colors. No odd eyes that I can tell. The other side of his face is like a tan/caramel color.

Any thoughts?

I wonder if that would be considered a tri-color, either way I'd keep him (if only as a pet)

WANT! Send him here if you want!

Looks like a chimera to me. Looks like mink and beige maybe.

Cool rat, it's a shame that chimeras don't produce more chimeras. :(

Oh wow, that was just an educated guess I took on him after seeing the chimeric mice.

Pretty cool. I am still going to do some experimental breeding just in case he isn't chimeric and it's something else. I know chimerism is not genetic.

Through breeding could we determine if he is chimeric or not? I guess it would just depend on what set of DNA is linked to what system of cells.

Correct me if I am wrong, but because he is from a blue mom, making him 100% het blue, if he never produced blue offspring with a visible blue then we can safely say that he is chimeric and the DNA from the non blue parent (dad) is present in his sperm?

Right? Fingers crossed that it's that easy?

If it was mink and beige would it not have ruby or red eyes?

-squint- Is it black?

I believe both eyes are black. I will bring out our nearly dead flash light and nearly blind him to see if one is really dark ruby. I was spending time with all the rats last night and I do have some that are odd eyed in just the right light but I haven't noticed on him.

The chimerism may play a role in the one eye not being ruby/red you think?

I'm sorry I thought the rat was brown, but on a different monitor now it's looking like a black.
So what else was in the litter with this rat?



Usually, a chimera is 2 colours that are both genetically possible from the pairing.
For example, if you had a litter of black and blue babies, you could have a chimera which is black and blue. (wouldn't that look neat!?)

Other litter mates were black hoodeds and some black variberks.

He is about to need a home... He is constantly either picking fights with his girls or they are beating up on him. I am getting rather tired of it.

That is one interesting boy you've got there!! I haven't seen anything quite like him and "Chimera" is new to me. I love the weird!!

So called "English" Minks have black eyes. I have both the "English" Mink variety as well as the more commonly seen Ruby/Red Eyed.

My guess would be Black and English Mink.

I would see what color that pup grows into before deciding. Cute pup!!

That's a variberk I believe, a beige probably.

it is a champagne hooded. grandpa was a champange. they are non-agouti

Your rat, TruedatxD, does not display any physical attributes of a chimera.

The vast majority of chimeras, display in ways that you cannot see. Such as, part of their internal organs may be chimeric, or the roof of their mouth might be chimeric. It's very rare to get a chimera that displays on the coat.
In theory, you could also get a chimera that is half dumbo and half normal eared, wouldn't that be interesting? :P

Wow, what an amazing rat! So jealous.

Sorry for "reviving" old thread, I found it via random picture search on google...

Anw, I'm really interested how your rat turned up? :D
Did he/she had litter and what kind of?

Cause I have almost exact one!
And I'm from Croatia x)

Here's my Loki

People on NFRS and other forums offered me their litters and money for him but, for a start, we weren't even close for exchange x)
wouldn't give him anw :P

Most of them said he wouldn't be fertal but here's some of his baby's from different litters :D

He came from a snake breeder so I don't know his parents but he sure has a lot of different genetic material lol

So I am really interested how yours turned up to be :D

Those are really nice Rexes. I don't know how often Angela logs in here any more but I just wanted to say that.

Slania - there are somatic mutations, where the mutation occurs only in the somatic (non-reproductive) cells. This can cause a visible change, such as a patch of color that is different from the rest of the body. Then there are chimeras, where 2 embryo actually merge together to create one. In such an animal there would be genetic material from two different individuals. If that occurred involving the skin and fur cells, then you can see different patches of color. Neither of these are particularly common, and neither is genetically passed on to offspring either. Depending on how each individual is affected by their "condition" they may or may not be fertile to produce offspring.

Very cute rats you have! That blue dumbo rex has my heart. If only I could find some good rex locally.

The last I heard is he never bred for his new owner. Definitely the same thing at work between our two though.
