The differences and similarities between sexual selection, disruptive selection, and nonrandom mating. Introduction: Microevolution is the evolution of an organism by showing variations in traits governed by genotype as well as phenotype , and change in allele frequency in subsequent generations. Some of the examples of microevolution are genetic drift, mutation, gene flow, natural selection, sexual selection, and nonrandom mating. The process of natural selection favors the desirable genetic variations for the survival and reproduction of organisms and contributes to evolution. This theory focuses on the phenotypic characteristics of organisms rather than the genotype.
