n rabbits, black fur is dominant to white fur. As a rabbit breeder, you crossed a BB male with a Bb female, please complete the Punnett square for the possible genotypes of the offspring. Then complete, the percent chance for the phenotypes of the offspring.

To complete the Punnett square for the possible genotypes of the offspring, we will label the rows with the male rabbit's genotypes (BB) and the columns with the female rabbit's genotypes (Bb):
B B
B | BB BB
b | Bb Bb
The possible genotypes of the offspring are: BB, Bb, Bb, and bb.
To calculate the percent chance for the phenotypes of the offspring, we need to consider the dominance of black fur (B).
BB represents a black rabbit with two dominant alleles, so it will have black fur. Therefore, the percent chance for black fur is:
100% chance for black fur (offspring 1 and offspring 2).
Bb represents a black rabbit with one dominant allele and one recessive allele, so it will also have black fur. Therefore, the percent chance for black fur is:
100% chance for black fur (offspring 3).
bb represents a white rabbit with two recessive alleles, so it will have white fur. Therefore, the percent chance for white fur is:
100% chance for white fur (offspring 4).
In summary, the percent chance for the phenotypes of the offspring is:
Black fur: 100%
White fur: 100%
