Black fur x white fur= gray fur in the offspring of rabbits, BB x WW =BW
A
codominance
B
dominant genes
C
incomplete dominance
D
Mendel genetics
Explanation: 

Detailed explanation-1: -Complete answer: The black is dominant over the white colour. The heterozygous condition in mouse coat colour is represented as (Bb) whereas the homozygous white colour is represented as (bb).

Detailed explanation-2: -The coat colour of rabbits is expressed through incomplete dominance. The coat colour can be dark brown, light brown, or white. There are 81 dark brown rabbits, 150 light brown rabbits, and 69 white rabbits.

Detailed explanation-3: -Explanation: Codominance means that more than one type of dominant allele for the same gene is present. If both black and white fur are dominant, then heterozygous (Aa) offspring would be spotted with black and white.

Detailed explanation-4: -Brown fur is dominant to white fur in a species of rabbit and is represented with the alleles “B” and “b". What are the resulting percentages of genotypes of a cross between a homozygous dominant parent and a heterozygous parent? Explanation: The answer is 50% BB and 50% Bb, as shown in the punnet square below.
