Problem:

Question: Suppose a plant was true-breeding for orange flowers, a dominant trait.

a. Crossing the plant to a heterozygote would produce 100% orange-flowered progeny.

b. Crossing the plant to a heterozygote would produce 50% orange-flowered progeny.

c. Crossing the plant to a homozygous recessive would produce 50% orange-flowered progeny.

d. Self-pollination of the plant would produce a 3:1 ratio of dominant:recessive traits.

e. The orange flower trait will increase in frequency over time.

Give reasoning with your answer.
