Question

If a population is in Hardy-Weinberg equilibrium, which of the following statements is correct?

1)

Each allele will be present at a 50% frequency.

2) Allele frequencies can vary from generation to generation, but the average frequency must remain constant.

3) the size of the population must remain constant from generation to generation.

4) Allele frequencies must remain the same from generation to generation.

5) The rate of change of allele frequencies must be greater than 1 percent from generation to generation.

Answer 1

The correct statement for a population in Hardy-Weinberg equilibrium is that allele frequencies must remain the same from generation to generation.Allele frequenciesmust remain the same from generation to generation.

Step-by-step explanation:

If a population is in Hardy-Weinberg equilibrium, which of the following statements is correct? The correct answer is 4)

Allele frequenciesmust remain the same from generation to generation. In a population at Hardy-Weinberg equilibrium, genetic equilibrium is achieved by satisfying five main criteria. These include no mutation, no migration (gene flow), a very large population size to prevent genetic drift, random mating, and no natural selection. When these conditions are met, the allelic and genotypic frequencies in the population do not change over time, and the population does not evolve. Therefore, the allele frequency in a given population would be stable across generations unless evolutionary forces are at play.
