A panmictic population is one where all individuals are potential partners. This assumes that there are no mating restrictions, neither
genetic or
behavioural, upon the population, and that therefore all recombination is possible. The
Wahlund effect assumes that the overall population is panmictic.In
genetics, random mating (or panmixus) involves the
mating of individuals regardless of any physical, genetic, or social preference. In other words, the mating between two organisms is not influenced by any environmental, hereditary, or social interaction. Hence, potential mates have an equal chance of being selected. Random mating is a factor assumed in the
Hardy-Weinberg principle. Random mating is a separate assumption than
natural selection. It is possible to have random mating at the same time the population is undergoing viability selection, for example.

Totally haphazard mating with no regard to the genetic makeup (genotype) of the mate so that any sperm has an equal chance of fertilizing any egg. This rarely, if ever, occurs but the concept is impoortant in population genetics. Also called panmixus.
Mating without any preference for mates. One of the assumptions of Hardy-Weinberg equilibrium (see assortative mating).
