Question

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 causes the gamete to be unable to receive a dominant allele for pea shape. B. It decreases the probability that the gamete will receive a dominant allele for pea shape. C. It has no effect on the probability of the gamete receiving a dominant allele for pea shape. D. It increases the probability that the gamete will receive a dominant allele for pea shape.

Answer 1

The correct Answer is B.

Answer 2

C. It has no effect on the probability of the gamete receiving a dominant allele for pea shape.

Step-by-step explanation:

Gametes are the cells responsible for sexual reproduction. They are also called sex cells and merge in the process of fertilization to produce the zygote, which in turn gives rise to the embryo, generating a new being.

Gametes have half the chromosomal set of a species, and they are responsible for receiving alleles that will dictate the dominant and recessive characteristics. However, gametes receive alleles at random, so we can say that in the case shown in the question above, the alternative that answers your question correctly is the letter C.
