| random mating | 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. (12 Dec 1998) |

| random mating equilibrium | <genetics> In a population containing the genotypes of AA, aa, and Aa, the frequency of AA will be p2, the frequency of aa will be q2, and the frequency of Aa will be 2 pq at equilibrium, where p is the frequency of A and q is the frequency of a. By the Hardy-Weinberg law, a ramdonly-mating population will eventually reach these frequencies and be at this equilibrium as long as there are no selection pressures on the population. (09 Oct 1997) |
| mating | The pairing of male and female for the purpose of reproduction. (05 Mar 2000) |
| mating isolate | A population separated from its neighbors by any means so that all or most matings occur within the population group. (05 Mar 2000) |
| mating type gene | Genes that, in Saccharomyces cerevisiae specify into which of the two mating types (a and _) a particular cell falls. Only unlike mating type haploids will fuse. The interest derives from the way in which mating type is switched, the existing gene is removed and a new gene, derived from a (silent) master copy elsewhere in the genome is spliced in. Later this gene will in its turn be replaced by a new copy of the old gene, also derived from a silent master. The a and _ genes code for pheromones that affect cells of the opposite mating type. Similar mating type genes are known from other yeasts and the switching mechanism (cassette mechanism) may be used more generally. (18 Nov 1997) |
| nonrandom mating | Selection of a mate with preference for (or aversion to) a particular genotype, i.e., nonrandom mating. Synonym: nonrandom mating. (05 Mar 2000) |

|
| assortative mating |
Nonrandom mating on the basis of phenotype; usually used for positive assortative mating, the propensity to mate with others of like phenotype.

|
| assortative mating |
Individuals similar (positive assortative mating) or dissimilar (negative) to each other are more likely to mate (or to be mated) than if mates were chosen at random.
