What is the term used to describe the process by which advantageous traits become more common in a population over time?

Genetic drift: It is a random process of evolution that can lead to a change in the gene pool of a population over time. It occurs when chance events, such as genetic mutations or environmental factors, affect the survival and reproduction of individuals in a population. Genetic drift can result in the loss of genetic diversity within a population and can increase the frequency of certain alleles while decreasing others.

Mutation: It is a spontaneous and random change in the DNA sequence of a gene. Mutations can arise due to errors in DNA replication or as a result of exposure to mutagens, such as radiation or chemicals. Mutations can be beneficial, harmful, or neutral in their effects on an organism. Beneficial mutations can increase an organism's chances of survival and reproduction, while harmful mutations can decrease those chances.

Natural selection: It is the process by which certain traits become more or less common in a population over time, depending on their effects on an organism's survival and reproduction. Natural selection occurs when individuals with advantageous traits are more likely to survive and reproduce than those with less advantageous traits. This results in the accumulation of beneficial traits in a population over time, as well as the removal of harmful traits.

Gene flow: It is the movement of genes from one population to another. Gene flow occurs when individuals from one population migrate and breed with individuals from another population. Gene flow can introduce new alleles into a population and increase genetic diversity, or it can reduce genetic differences between populations. Gene flow can be affected by factors such as geographic barriers and migration patterns.
