Lupe grows pea plants in her garden. The pea plants have flowers that can be either purple or white, with purple color being dominant to white color. The peas produced by Lupe's pea plants can also be either round or wrinkled, with round peas being dominant to wrinkled peas.

Lupe crosses two pea plants that are heterozygous for both traits. If a gamete from this cross receives a dominant allele for flower color, how does this influence the probability of the gamete receiving a dominant allele for pea shape?

(Assume that the genes for flower color and pea shape follow the law of independent assortment.)
A.
It has no effect on the probability of the gamete receiving a dominant allele for pea shape.
B.
It increases the probability that the gamete will receive a dominant allele for pea shape.
C.
It causes the gamete to be unable to receive a dominant allele for pea shape.
D.
It decreases the probability that the gamete will receive a dominant allele for pea shape.
