Genetic drift is a random process that can lead to the loss of genetic diversity in small populations. The low number of inversion types seen in North American populations of Drosophila suboscura is likely due to genetic drift, as these populations are relatively small compared to other global populations of the species. Nonrandom mating, heterozygous advantage, and sexual selection are all factors that could potentially maintain or increase genetic diversity in a population, while mutation may lead to the creation of new genetic variants. However, none of these factors would necessarily explain the low number of inversion types specifically seen in North American populations.
