baby rat colors

[Troya]

I have a 12days old baby rats. Please help with colors! one is black hooded, but what color is other babies? Mother is black with white spot on belly, father beige hooded. One of babies looks hairless (does it mean that both parrents carry hairless gene?)

I'm seeing mink and british blue (aka american blue), as well as the hairless who is probably the same as the father.

Yes, both parents must be carrying hairless to produce a hairless baby.
