With a small population size, genetic drift becomes more likely to occur. This is because genetic variation is reduced, and chance events can have a bigger impact on the gene pool. Gene flow may not occur as often, as there may not be many opportunities for individuals to move in or out of the population. Mutations may happen, but they may not have a large impact on the gene pool unless they are beneficial and are selected for. Sexual selection may also occur, but it may not have as big of an impact on the gene pool compared to genetic drift.
