A snapdragon is a type of flowering plant. In snapdragons, the allele for red flowers (R) is incompletely dominant over the allele for white flowers (r).

Part A: Predict the phenotype that will be expressed by a snapdragon that is heterozygous for flower color (Rr).

Part B: Suppose two snapdragons that are heterozygous for flower color (Rr) are crossed. Predict the percentage of each possible phenotype that will result from this cross. In your answer, be sure to explain the reasoning behind your prediction.

Part C: A gardener wants to produce a generation of snapdragons that displays only the phenotype associated with the heterozygous genotype (Rr). Determine the genotypes and phenotypes of the snapdragons the gardener should cross to accomplish this goal. In your answer, be sure to explain the reasoning behind your decision.

Type your responses to parts A, B, and C in the box below.
