Ablack rooster mates with a white hen. based on their genotypes, the chance that the offspring will be checkered is 100 percent. what is the roosters genotype? what is the hens genotype?

Rooster: BB         Hen: WW

Explanation:

Let's assign B for Black and W for White.

The scenario states that the chance that the offspring will be checkered is 100%. This means that both black and white are expressed at the same time. This phenomenon is called INCOMPLETE DOMINANCE. This happens when one of the alleles do not completelt mask the other, so instead of getting the trait of one of the parents, a new type of phenotype is formed.

The only way for the offsprings to ALL turn out checkered is if the parents were homozygous for their specific traits. So look at the Punnet below:

      W     W

B   BW   BW

B   BW   BW

Both are homozygous dominant because if either of the color were recessive, it would be masked.
