Question
Genetic drift and migration are mechanisms of evolution but are not mechanisms of natural selection.Group startsTrue or False
Solution
True. Genetic drift and migration are indeed mechanisms of evolution, but they are not mechanisms of natural selection. Natural selection involves the survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution. On the other hand, genetic drift is an evolutionary change in allelic frequencies within a population that occurs due to chance, and migration (or gene flow) is the transfer of genetic variation from one population to another. While these processes can cause changes in the genetic composition of a population, they do not involve the process of differential survival and reproduction that characterizes natural selection.
