The most likely explanation for the observation that round is dominant to wrinkled in Mendel's peas is

a. the wrinkled allele encodes a functional enzyme, the round allele encodes a defective enzyme, and the round trait could arise with only one functional gene for the enzyme.

b. the round allele has an uppercase letter.

c. the round allele poisons the wrinkled allele.

d. the wrinkled allele encodes a functional enzyme, the round allele encodes a defective enzyme, and the wrinkled trait could arise with only one functional gene for the enzyme.

e. the round allele encodes a functional enzyme, the wrinkled allele encodes a defective enzyme, and the round trait could arise with only one functional gene for the enzyme.

The correct option is e) the round allele encodes a functional enzyme, the wrinkled allele encodes a defective enzyme, and the round trait could arise with only one functional allele for the enzyme.

Explanation:

The allele in a gene which suppresses the effect of the other allele is known as the dominant allele. The allele which gets masked by the dominant allele is called as a recessive allele.

As we can observe that only one allele was enough to show the round types, hence the round types should be considered dominant.

Both the alleles should be recessive for the wrinkled trait to occur. Hence, it is a recessive trait.
