A mouse.

(Sorry! Couldn't help it...)

If she is tan, she's probably diluted on the c-locus with something like beige or chinchilla, and then again on another locus (such as Ay/*, red) that would wipe out what color the c-locus had left.

Depending on what her babies are (do you know the father?) and how well the pictures turn out, we could tell you for certain.

I can't say for sure what she is (when she gives babies that should help), but I can say what she's not. She's not a PEW.

She's also not an undermarked brindle because you're in Scotland. The brindle windyhill is talking about occurs only in Australia and the US.

the first pic is a moderately good marked black tan.

Nope, he's marked. "Black tan" is a show category and he could not be shown as a black tan due to the white markings. He's still a very cute mouse!

For example, if you had chocolate babies you'd know she was a very light champagne (plus something else) tan. If she had red babies, you'd know she was red (fawn) diluted by something...and so forth.

You're very welcome! All of my mice come from known lines so I only very rarely get a "surprise" where I have to figure out the genetics. It's fun.

Then she's probably not pregnant. If you still want to, I'd try her again.
