answer would be option - A .0%

because the BB is dominant character

Answer: 0%

Explanation:

When the black dog with genotype BB mates with a white dog of genotype bb, the cross is shown as follows:

BB X bb ----> Bb Bb Bb Bb

From the cross, it can be seen that all the progenies will have the genotype Bb.

Since B is dominant over the allele b, all the progenies with genotype Bb will have the phenotype black.

Therefore, the probability of white puppies is 0%.
