Question

populations. in these populations, chance events can lead to significant changes in allele frequencies, potentially causing the loss of alleles and reduced genetic diversity. this can have consequences for adaptation and overall population health. which factor affects small populations more? genetic drift mutation natural selection

Explanation:

In small populations, chance - based genetic drift can cause significant allele - frequency changes, loss of alleles, and reduced genetic diversity more than mutation or natural selection.

Answer:

genetic drift
