Question

a black rooster Mated with a white hen. based on genotypes, the chance that the offspring will be checkered is 100 percent. what is the roosters genotype? what's the hens genotype?

Answer 1

I feel like both are dominant since the offspring is checkered

Answer 2

Answer:

The genotypes of the rooster and the chicken are homozygous and that of their offspring is heterozygous.

This case is called codominance, where the offspring receives an allele from each parent, from the rooster and the hen, because there is codominance, so neither allele is recessive and the phenotype of both alleles is expressed so the phenotype of the offspring is checkered.

We can say then that the chicken and the rooster have equal strength between their alleles. in the cases of codominance the laws of mendel do not apply.
