Black, although it's actually dark brown, there is no such thing as black hair.

Probably black, since it has 2 dominant alleles. In sheep, however, white is dominant over black, so a sheep with genotype BB would be white, and its first-generation offspring would be, too. If the only information given is what you've posted, I would have to say D, because we don't know what the expression of this genotype is in mice.

The gene for White would be W or w. So if it is BB then it has dominant for black. But like the one above me you'd have to know what is dominant in mice.

D) cannot be determined.
BB is dominate homozygous therefore, It is either black or it is white.
