What Phenotypes Could the Kittens Exhibit?

The kittens could exhibit gray or white fur.

When a gray cat and a white cat have kittens, the phenotypes that the kittens could exhibit are influenced by the genetic possibilities of the parents. In this scenario, black fur is dominant, white fur is recessive, and gray fur is intermediate. Gray cats possess one allele for black fur and one for white fur, represented as 'Bb', while white cats have two alleles for white fur, represented as 'bb'.

To determine the potential phenotypes of the kittens, we can use a Punnett square. Let's represent black as 'B' and white as 'b'.

Using the Punnett square:

Gray (Bb) | B | b |

White (bb) | Bb | bb |

From the Punnett square, we can see that the resulting kittens can have 'Bb' (gray) or 'bb' (white) alleles. Therefore, the kittens could exhibit gray or white fur, making option A - gray or white fur - the correct answer.
