WebMar 5, 2024 · Natural selection will be discussed in the "Natural Selection" concept. Mutation. Mutation creates new genetic variation in a gene pool. It is how all new alleles first arise. In sexually reproducing species, the mutations that matter for evolution are those that occur in gametes. ... Genetic Drift. Genetic drift is a random change in allele ... WebGenetic drift is a random process that can lead to large changes in populations over a short period of time. Random drift is caused by recurring small population sizes, severe reductions in population size called …

WebAll of these mechanisms can cause changes in the frequencies of genes and other genetic elements in populations, and so all of them are mechanisms of evolutionary change. However, natural selection and genetic drift can only change the frequency of different genes and genetic elements (e.g., making wide beaks or green beetles more or less ...
