as·sort·a·tive mat·ing

(ă-sōrt'ă-tiv māt'ing)
Selection of a mate with preference for (or aversion to) a particular genotype, i.e., nonrandom mating.

assortative mating

a type of cross in which the choice of partner is affected by the GENOTYPE, i.e. mating is nonrandom. For example, human matings are often assortative with respect to racial features since persons of one racial group may tend to have children by partners of the same group. This choice of mates means that genotypic frequencies predicted by the HARDY-WEINBERG LAW may not be found. See also RANDOM MATING, INTERBREED.

assortative mating

sexual reproduction in which the pairing of male and female is not random.
