Gene frequencies are the frequencies and occurrences of the alleles in the population. Small populations allow the gene frequencies to change by the chance. Thus, option A is correct.
<h3>What is gene frequency?</h3>
The gene frequency is also called the allele frequency which shows the expression of the particle allele and trait in a population. It occurs in the smaller population by chance.
The smaller population has a low number of individuals as compared to a larger population. They show a greater number of genetic drift that show evolutionary changes at a faster rate.
Therefore, option A. smaller populations show gene frequencies.
