Question

In rabbits, black fur (B) is dominant to white fur (b). A purebred ( homozygous) black-furred male is bread with a female that has the recessive white fur.

Answer 1

B is the dominant trait (black fur)

b is the recessive trait (white fur)

The cross of BB (purebred homozygous black fur) to bb (recessive white fur) will produce Bb 100% hybrid genotypes. The probability of black fur is 100% and the probability of white fur is 100% since the result of the cross are all hybrid offspring. All hybrid offspring can either have black or white fur.
