Question

Which of the following statements is a correct explanation for the observation that all offspring exhibit a phenotype for a particular trait that appears to be a blend of the two parental varieties?
A) The genes for the trait are recessive in both of the parents.B) The genes for the trait are dominant in both of the parents.C) The genes are linked and do not separate during meiosis.D) Neither of the parental genes is dominate over the other.

Answer 1

Answer:

D) Neither of the parental genes is dominate over the other.

Explanation:

Since the trait on the offspring is a mixture from both parent, it means that neither of the alleles from both parents is completely dominant over the other. Instead, each of the alleles contributes equally to the trait of the offspring.

This effectively explains the fact that each trait exhibited by offspring is a blend of the traits from the two parents.

The correct option is D.
