Mutation. Makes new alleles from old. Gene duplication events provide the opportunity for a gene to be repurposed. Viral lysogeny can assist with lateral gene transfer between species. 2. Gene flow (formerly known as migration). Immigrating organisms can bring new alleles into a population. Emigrating animals can remove their alleles from a small population. 3. Genetic drift. Chance events and accidents can amplify or remove alleles from a small population. 4. Selection. Alleles for traits that provide their owners with better "fitness" for the local environment or local population may increase in frequency in the population. Alleles for traits that decrease the fitness of their owners may decrease in the population.<br><b>References : </b><br> 1. Mutation. Makes new alleles from old.
