In this case, we are looking at a simple Mendelian trait where fur color is determined by a single pair of alleles. The black dog has the genotype BB (homozygous dominant for black fur), and the solid white dog has the genotype bb (homozygous recessive for white fur).
When the black dog (BB) mates with the white dog (bb), we can set up a Punnett square to determine the genotypes of the puppies:
- The black dog can only pass on the B allele (since it is homozygous BB).
- The white dog can only pass on the b allele (since it is homozygous bb).
The resulting combinations for the offspring would be:
- B from the black dog and b from the white dog, resulting in Bb (black fur).
Since every puppy will be Bb, which corresponds to black fur due to the dominance of the B allele over the b allele, none of the puppies will be white.
Therefore, the probability that this match will produce puppies that are also white is:
A 0%.
