Random mating
(Redirected from Nonrandom mating)
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. However, when evolution or natural selection is occurring, random mating is not in effect because the basis of evolution is the selection of traits favorable to survival. Thus, random mating is not possible during evolution.
