WebGene flow may change the frequency and/or the range of alleles in the populations due to the migration of individuals or gametes that can reproduce in a different population. The introduction of new alleles increases variability within a population and allows for new combinations of traits.

These mechanisms are called the “forces of evolution” and together they can account for all the genotypic variation observed in the world today. WebFeb 19, 2024 · The process of evolution occurs only in populations and not in individuals. A single individual cannot evolve alone; evolution is the process of changing the gene frequencies within a gene pool.
