The correct answer would be a.) 0%

The gametes produced by Bb would be B and b.

Only one type of gamete would be produced by BB that is, B.

Thus the cross would result in the production of offspring with two types of genotypes BB and Bb.

Thus, all the offspring would express dominant trait.

So, if grey is the dominant trait then all the offspring would be grey that is, 100% and if grey is recessive then none of the offspring would be grey that is, 0%.

In general, grey is a recessive trait and thus, none of the offspring would be grey.
