Genotype and Phenotype of the chicken

BW - black and white speckled

Since the chicken appears to have some parts of its feathers that are white and some that are black, both alleles (B and W) dominate, meaning the characteristic or trait is demonstrating

Codominance

co- means jointly or mutually, so it literally means the alleles are mutually dominant

Genotype and Phenotype of the cows from top to bottom

WW - white

RR - red (I know the cow looks brown, but this reddish brown color in the hairs is known as red to bovine geneticists)

RW - roan - red and white speckled

Since the RW cow appears to have some parts of its hide that have white hairs and some that have the reddish brown hairs, both alleles (R and W) dominate, meaning the characteristic or trait is demonstrating

Codominance

co- means jointly or mutually, so it literally means the alleles are mutually dominant

Genotypes and Phenotypes from left to right

WW (white), RR (red), RW (pink)

Since the RW plant is in between-looking (pink is in between red and white), neither allele (R or W) dominates, meaning the characteristic or trait is demonstrating

Incomplete Dominance

Genotype and Phenotype of this plant

RW (red and white speckled)

Since the RW plant appears to have some flowering parts that are white and some that are red, both alleles (R and W) dominate, meaning the characteristic or trait is demonstrating

Codominance

co- means jointly or mutually, so it literally means the alleles are mutually dominant
