Question

multiple choice question
what can likely happen as a result of genetic drift to uncommon alleles in small, isolated populations?
they are likely to increase in heterozygotes.
they are likely to be lost.
they are likely to increase in frequency.
they are likely to mutate in the next generation.

Explanation:

Genetic drift is a random change in allele frequencies. In small, isolated populations, uncommon alleles are more vulnerable to random events that can cause their loss due to sampling error.

Answer:

They are likely to be lost.
