Question

multiple choice question
which evolutionary mechanism causes beneficial traits that are heritable to become more common in a population?

o migration
o natural selection
o nonrandom mating
o horizontal gene transfer
o genetic drift

Explanation:

Natural selection favors heritable traits that increase an organism's fitness (ability to survive and reproduce). Beneficial traits give individuals an advantage, allowing them to pass on these traits more frequently to the next - generation, making them more common in the population over time. Migration can introduce new traits but not specifically target beneficial ones, non - random mating affects genotype frequencies rather than selecting for beneficial traits, horizontal gene transfer is more about the transfer of genes between different organisms, and genetic drift is a random change in allele frequencies not related to trait benefit.

Answer:

Natural selection
