Question

Individuals that carry a particular allele may have more descendants than other individuals, resulting in the allele becoming more common. Which process causes random alleles to become more common within a population?

gene shuffling


directional selection


natural selection


genetic drift

Answer 1

genetic drift

Step-by-step explanation:

When genetic drift happens, a random allele becomes more common just by chance. Unlike natural selection, there is no benefit from the random allele that helps the organism to have a better survival rate in genetic drift. It simply coincidence without any cause. Genetic drift will less likely happen if the population bigger compared to a smaller population.
