So my blue girls did have their litters and the colors are interesting. I looked at them all closely and if both parents are satin, then the babies are satin as well, correct? Some of them also appear to be long-haired (some hairs are much longer than normal) I will take better pictures when I find my camera. As far as color, 5 females appear to be black selfs. 3 females and 4 males appear to be fox (black on top, white on the bottom). So can anyone shed some light on the genetics of these mice? Since the mothers are blue, then all these babies carry the blue gene, correct? And since I didn't get any blue babies, then the male (himalayan) does not carry blue.
