| 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.

| assortative mating | Selection of a mate with preference for (or aversion to) a particular genotype, i.e., nonrandom mating. Synonym: nonrandom mating. (05 Mar 2000) |
|---|---|
| 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) |
| random | 1. Force; violence. "For courageously the two kings newly fought with great random and force." (E. Hall) 2. A roving motion; course without definite direction; want of direction, rule, or method; hazard; chance; commonly used in the phrase at random, that is, without a settled point of direction; at hazard. "Counsels, when they fly At random, sometimes hit most happily." (Herrick) "O, many a shaft, at random sent, Finds mark the archer little meant !" (Sir W. Scott) 3. Distance to which a missile is cast; range; reach; as, the random of a rifle ball. 4. <chemical> The direction of a rake-vein. Origin: OE. Randon, OF. Randon force, violence, rapidity, a randon, de randon, violently, suddenly, rapidly, prob. Of German origin; cf. G. Rand edge, border, OHG. Rant shield, edge of a shield, akin to E. Rand, n. See Rand. Going at random or by chance; done or made at hazard, or without settled direction, aim, or purpose; hazarded without previous calculation; left to chance; haphazard; as, a random guess. "Some random truths he can impart." (Wordsworth) "So sharp a spur to the lazy, and so strong a bridle to the random." (H. <medicine> Spencer) Random courses, stonework consisting of stones of unequal sizes fitted together, but not in courses nor always with flat beds. Source: Websters Dictionary (01 Mar 1998) |
| random allocation | A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects. (12 Dec 1998) |
| random amplification of polymorphic DNA | <molecular biology> A term originally invented by polymer chemists to describe a disordered tangle of a linear polymer chain with curved sections. In DNA parlance the random coil refers to the structure that results from melting or other forms of separation of the double helix, i.e. Helix coil transition. (18 Nov 1997) |
| random amplified polymorphic DNA technique | Technique that utilises low-stringency polymerase chain reaction (pcr) amplification with single primers of arbitrary sequence to generate strain-specific arrays of anonymous DNA fragments. Rapd technique may be used to determine taxonomic identity, assess kinship relationships, analyze mixed genome samples, and create specific probes. (12 Dec 1998) |
| random coil | A structure of a macromolecule (typically, a biopolymer) which changes with time. (05 Mar 2000) |
| random mechanism | A scheme for substrate binding and product release for a multisubstrate enzyme; for a two-substrate two-product enzyme with this mechanism, either substrate can bind first and, after the reaction has taken place, either product can be the first to dissociate from the enzyme. Brain hexokinase has a random mechanism. More complex random mechanisms exist for enzymes having more than two substrates. (05 Mar 2000) |
| random pattern flap | A flap in which the pedicle blood supply is derived randomly from the network of vessels in the area, rather than from a single longitudinal artery as in an axial pattern flap. (05 Mar 2000) |
| random sample | A group selected randomly, solely by chance. (12 Dec 1998) |
| random sampling | A selection of elements by a formal randomizing device for purposes of inference about a population of inference from that population in such a way that the probability of each possible outcome may be precisely specified in advance; the inferences are necessarily stochastic. (05 Mar 2000) |
| random variable | A variable that may assume a set of values, each with fixed probabilities or probability densities (its distribution), in such a way that the total probability assigned to the distribution is unity; the random variable may be discrete, continuous, or mixed discrete-continuous.
