What does the principle of genetic equilibrium state about allele frequencies in a population?

Options

  1. AThey fluctuate constantly
  2. BThey are stable and constant from generation to generation
  3. CThey always increase over time
  4. DThey decrease over time

Correct answer

B. They are stable and constant from generation to generation

Step-by-step solution

This principle says that allele frequencies in a population are stable and is constant from generation to generation. The gene pool (total genes and their alleles in a population) remains constant. This is called genetic equilibrium. Sum total of all the allelic frequencies is 1. Individualfrequencies, for example, can be named p, q, etc. In a diploid, p and q represent the frequency of allele A and allele a. The frequency of AA individuals in a population are simply p2. This is simply stated in another ways, i.e.,
