Question

Part 1: Incomplete Dominance—Predicting Flower Color in Snapdragons
Snapdragons are popular garden plants that produce brightly colored flowers. When a plant that is homozygous for white flowers is crossed with a plant that is homozygous for red flowers, all offspring are pink. Snapdragons are an example of a plant that exhibits an inheritance pattern called incomplete dominance.

1. Determine the genotype of each parent plant and write them below. Use W to indicate the allele for white flowers and w to indicate the allele for red flowers.
Genotype of homozygous parent plant with white flowers:
Genotype of homozygous parent plant with red flowers:

2. Next, think about the gametes each parent plant will produce. List the allele in each gamete.
Parent plant with white flowers:
Gamete 1:
Gamete 2:
Gamete 3:
Gamete 4:
Parent plant with red flowers:
Gamete 1:
Gamete 2:
Gamete 3:
Gamete 4:

3. The two parent plants are the P generation, or parent generation. Create a Punnett square to show their offspring, the F1 generation.

4. What pattern do you notice in the genotypes of the F1 generation snapdragons?

5. What are the phenotypes of the F1 generation snapdragons?

Part 2: Incomplete Dominance—Predicting Flower Color in F2 Generation Snapdragons
Now, set up a cross of the offspring of the F1 generation and predict the traits of the F2 generation.

1. What are the genotypes of the F1 parent plants?
Genotype of F1 parent plant 1:
Genotype of F1 parent plant 2:

2. Next, think about the gametes each parent plant will produce. List the allele in each gamete.
F1 parent plant 1:
Gamete 1:
Gamete 2:
Gamete 3:
Gamete 4:
F1 parent plant 2:
Gamete 1:
Gamete 2:
Gamete 3:
Gamete 4:
