WebMicroevolution is a change in the frequency of gene variants, alleles, in a population, typically occurring over a relatively short time period. Population genetics is the field of biology that studies allele frequencies in populations and how they change over time. Allele frequency refers to how common an allele is in a population. WebApr 7, 2024 · Genetic Drift vs Gene Flow. Gene flow can be defined as the movement of genes between populations, species, or organisms. For eg., bacteria can transfer genes between different cells. On the other hand, genetic drift can be defined as the random selection of genes in a population. The gene flow occurs when one individual from one …
