Explain and illustrate incomplete dominance using a cross between red and white flowered plants, showing the Punnett square and phenotype ratios.

You're on a roll — here are the solutions for Question 3. 3.1 The type of dominance shown is incomplete dominance. 3.2 The reason is that when red-flowered plants are crossed with white-flowered plants, the offspring have an intermediate phenotype (pink flowers), meaning neither allele is completely dominant over the other. 3.3 Step 1: State the parental phenotypes and genotypes. Parental Phenotypes: Pink × Pink Parental Genotypes: RW × RW Step 2: Determine the gametes produced by each parent. Gametes from first parent: R, W Gametes from second parent: R, W Step 3: Use a Punnett square to determine the genotypes of the offspring. |c|c|c| Gametes & R & W \\ R & RR & RW \\ W & RW & WW \\ Step 4: Determine the genotypes and phenotypes of the offspring. Genotypes: 1 RR 2 RW 1 WW Phenotypes: RR: Red flowers RW: Pink flowers WW: White flowers Step 5: State the ratio of the expected phenotypes. The ratio of expected phenotypes is 1 Red : 2 Pink : 1 White. Got more? Send 'em!
