GENES IN POPULATIONS
... These are: Natural Selection, Gene flow, Genetic drift, and Mutation. The first three processes cause change in the frequency of various genes in the population by “redistributing” the existing alleles, while the fourth, mutation, is the only one to introduce new variation into the gene pool. Natura ...
