Example of a genetic drift

WebThese modification of alleles is caused by evolutionary factors such as genetic drift and natural selection (Openstax, 2024). While natural selection guides the non-random disruptive process of evolution, genetic drift is the random variation in allele frequency that causes a population's gene pool to gradually skew. WebThe mechanism of evolution is a complex process that includes genetic variation, natural selection, genetic drift, gene flow, and environmental factors. Genetics and epigenetics, on the other hand, are two important mechanisms that contribute to the evolutionary process. Role of Genetics in Evolution. The basis of evolution is genetic variation.
