The evolutionary mechanism that most likely has contributed to this decrease in the population’s genetic diversity is genetic drift.
<h3>What is genetic drift?</h3>
Genetic drift is an overall shift of allele distribution in an isolated population, due to random fluctuations in the frequencies of individual alleles of the genes.
Genetic drift is one of the contributing factors of decrease in genetic variation among a population of organisms.
Therefore, the evolutionary mechanism that most likely has contributed to this decrease in the population’s genetic diversity is genetic drift.
