Question

What does genetic drift cause in a population, particularly in new samples of a population?

Options

• Elimination of all recessive alleles

• Changes in allele frequencies by chance

• Increases in mutation rates

• Stabilization of allele frequencies

Answer 1

Genetic drift causes random changes in allele frequencies, especially in small populations or in new samples of a population. These random fluctuations occur independently of selection or fitness, leading to unpredictable changes in allele composition.
