Which of the following scenarios would prevent a population from being in Hardy-Weinberg equilibrium?

A. The population is evolving, and natural selection is favoring one allele over another.
B. The population is stable, but younger generations of the population have a different allele frequency.
C. The population mates at specific times of the year, causing the population to fall out of equilibrium at that time of year.
D. The population will fall out of Hardy-Weinberg equilibrium if natural resources such as food are limited.

the Hardy–Weinberg equilibrium states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.

hope this helps:)

Answer:

(A) The population is evolving, and natural selection is favoring one allele over another.

Explanation:

According to Hardy-Weinberg equilibrium, the frequency (genetic variation) of population remains stable from one generation to the next generation.

The population will follow Hardy-Weinberg equilibrium if the population size is large, random mating, no natural selection , absence of mutation and gene flow.

If the population is evolving and natural selection favors an allele over another, this scenario will prevent that population to follow Hardy-Weinberg equilibrium.

Thus, the correct answer is option(A).
