Explanation Comments

A

It operates primarily through natural selection.

B

It always results in the evolution of traits that enhance survival.

What is the term for the process by which the frequency of an allele decreases due to selective pressure against it?

Explanation:

Which of the following is NOT a condition required for Hardy-Weinberg equilibrium?

Explanation:

Which of the following best describes the process of genetic recombination?

Explanation:

What is the term for the phenomenon where similar traits evolve independently in different species due to similar environmental pressures?

Explanation:

Which of the following statements about sexual selection is true?

Explanation:

What is the term for the process by which species gradually evolve differences in reproductive anatomy or behavior, leading to reproductive isolation?
