Codominant Incomplete Dominance Practice Worksheet Answer Key Fish Now

Match the following genotypes to the correct scale color.

Imagine a species of tropical fish where scale color is determined by incomplete dominance. Red scales WW: White scales RW: Pink scales Practice Problems Cross a Red fish with a White fish. Genotypes: RR x WW Offspring: 100% RW Phenotype: 100% Pink Cross two Pink fish. Genotypes: RW x RW Genotype Ratio: 1 RR : 2 RW : 1 WW Phenotype Ratio: 1 Red : 2 Pink : 1 White Case Study 2: Codominance (The "Mix") Match the following genotypes to the correct scale color

In a species of goldfish, scale pattern follows codominance. Gold scales (GG) Black scales (BB) Genotypes: RR x WW Offspring: 100% RW Phenotype:
