Re: MY RAT IS PREGO AND DUE TONITE!! What color will they be
With just that known information, they are all likel to be black genetically. Their phenotype might be REW or PEW, but you're still likely to end up with a lot of black.
If they share common genetics for other colors, you could end up with some beige, black, and white babies. It just kind of depends on their genetics. It's hard to tell when you don't know the genetic history of the parents.
I hope the babies are ok and don't inherit anything bad....
