Question

multiple choice question
which evolutionary mechanism causes beneficial traits that are heritable to become more common in a population?
nonrandom mating
horizontal gene transfer
genetic drift
natural selection
migration

Explanation:

Natural selection is the process by which organisms with heritable traits that are beneficial for survival and reproduction in a particular environment tend to survive and produce more offspring. This leads to an increase in the frequency of those beneficial traits in the population over time. Non - random mating affects the distribution of genotypes but not directly the prevalence of beneficial traits. Horizontal gene transfer is the movement of genetic material between organisms other than by vertical transmission. Genetic drift is a random change in allele frequencies. Migration is the movement of individuals between populations.

Answer:

Natural selection
