This black dog has the genotype of BB for fur color. The black dog mates and has puppies with a solid white dog. The white dog has the genotype bb. What is the probability that this match will produce puppies that are also white?

The genotype of the black dog is BB, which means it carries two dominant alleles for black fur color. The genotype of the white dog is bb, which means it carries two recessive alleles for white fur color.
When these two dogs mate, they can produce offspring with the genotypes Bb or bb. The Bb genotype would result in black fur color, while the bb genotype would result in white fur color.
Since the white dog has a genotype of bb, it can only pass on the recessive allele for white fur color. Therefore, all of the puppies produced from this mating will inherit one recessive allele for white fur color.
This means that the probability of producing puppies that are white is 100%.
Therefore, the answer is not provided in the available responses.

The probability that this match will produce puppies that are white can be determined by looking at the possible genotypes the puppies can have.
The black dog has a genotype of BB, meaning it carries two dominant alleles for black fur color. The white dog has a genotype of bb, meaning it carries two recessive alleles for white fur color.
When these two dogs mate, they can produce offspring with the genotypes Bb or bb. The Bb genotype would result in black fur color, while the bb genotype would result in white fur color.
Since the white dog has a genotype of bb, it can only pass on the recessive allele for white fur color. This means that in order for a puppy to have white fur, it must inherit the recessive allele from the white dog.
Therefore, there is a 50% chance that each puppy will inherit the recessive allele for white fur color from the white dog.
The answer is 50% (D).
