Answer: The probability of white puppies is Zero.
Genotype of the black dog is BB. This is a dominant trait, meaning that the presence of a single dominant allele ( Bb) will also give black color.
The genotype of white dog is bb. This is a recessive trait. It means that dog will express white color only if it is homozygous recessive ( bb).
When BB mates with bb, it results in all black puppies. This is so because the genotype of all puppies is Bb. Refer the Punnett square for this.
Thus, the probability that the match will produce white puppies is zero.
