Question

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? A) 0% B) 25% C) 40% D) 50%

Answer 1

answer would be option - A .0%

because the BB is dominant character

Answer 2

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%.
