Alleles are the alternative forms of genes present in an organism, which are inherited through sexual or asexual reproduction.

Today, we recognize that evolution takes place through a combination of mechanisms: mutation, genetic drift, gene flow, and natural selection. These mechanisms are called the “forces of evolution” and together they can account for all the genotypic variation observed in the world today. iris chicoutimi talbot
