Mutations – changes in the genetic sequence of DNA or RNA – are the raw material for evolution. Natural selection, genetic drift, and other evolutionary processes act on genetic variation – and that genetic variation starts with mutation. Even if a genetic variant is introduced to a population through migration, ultimately, that variant got its start …

WebThese are evolution by: mutation, genetic drift, gene flow, non-random mating, and natural selection. Each mechanism of evolution can be characterized by how it affects fitness, adaptation, the average phenotype of a trait in a population, and the genetic diversity of the population. Mutation generates variation WebMutation, migration, genetic drift, and natural selection are all processes that can directly affect gene frequencies in a population. Imagine that you observe an increase in the frequency of brown coloration genes and a decrease in the frequency of green coloration genes in a beetle population.
