The 5 agents of evolutionary change |
1. Mutation 2. Genetic drift- the random fluctuation of alleles due took chance ( small populations are more susceptible. 3. Non random mating. Assortative mating. Disassortive mating. 4. Gene flow- when individuals or gametes from one population enter another. 5. Selection |
