Answer:
genetic drift
Explanation:
The newly isolated population of beetle would have very different allele frequencies than the main population because of <u>genetic drift.</u>
Genetic drift refers to<u> a change in the frequencies of alleles in a population over generations brought about by pure chance</u>. Genetic drift can cause a bottleneck or founder effect. A <u>bottleneck effect</u> is a temporary decrease in the genetic diversity of a population while the<u> founder effect</u> refers to a decrease in the genetic variability of a new population formed from a small number of individuals that get separated from a larger population.
<em>Hence, the newly formed population of beetles would have lower allele frequencies than the main population due to the founder effect brought about by genetic drift. </em>
