Webnonrandom mating: selection of a mate with preference for (or aversion to) a particular genotype, that is, nonrandom mating. Synonym(s): nonrandom mating WebSep 4, 2024 · Non-random mating. Non-random mating won’t make allele frequencies in the population change by itself, though it can alter genotype frequencies. This keeps the population from being in Hardy-Weinberg equilibrium, but it’s debatable whether it counts as evolution, since the allele frequencies are staying the same.

WebAnimal mating systems. Three general mating systems, all involving innate and evolutionarily selected (as opposed to learned) behaviors, are seen in animal populations: monogamous, polygamous, and promiscuous.
