In pea plants there is a dominant allele (A) for green pods and a recessive allele (a) for yellow pods. Suppose a heterozygous plant is crossed with a plant that has yellow pods. Complete the sentence about this monohybrid cross with the correct terms.

The phenotype of the heterozygous plant is

Aa - a green pea pod plant

Explanation:

An heterozygous (Aa) crossed with homozygous recessive (aa), we have

Aa        x         aa

       1/2    Aa- a green pea pod plant

        1/2   aa- a yellow pea pod plant

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
