Codominance Incomplete dominance Flowers can be white, red or pink Codominance Incomplete dominance A chicken can be white, black, brown, red, or speckled. Codominance Incomplete Dominance In shorthorn cattle, when a red bull (RR) is crossed with a white cow (WW), all the offspring are roan—a spotted, red and white color. If a roan bull were crossed with a red cow, what would be the expected phenotypes of their offspring? Leave Blank R W R RR RW R RR RW Based on the Punnett Square above, fill in the following information. Percentage of red cows 50%Percentage of white cows 0%Percentage of roan cows 50% In snapdragons, flower color is controlled by incomplete dominance. The two alleles are red (R) and white (R'). The heterozygous genotype is expressed as pink. a. What is the phenotype of a plant with the genotype RR? redb. What is the phenotype of a plant with the genotype R'R'? whitec. What is the phenotype of a plant with the genotype RR'? pink
