| rural population | The inhabitants of rural areas or of small towns classified as rural. (12 Dec 1998) |
|---|---|
| p in population genetics | The frequency of the more common of two different alternative (allelic) versions of a gene. (the frequency of less common allele is q). (12 Dec 1998) |
| population | 1. <genetics> A stable group of randomly interbreeding individuals. 2. <statistics> The set of objects or individuals from which a random sample is drawn. Origin: L. Populatio, from populus = people (18 Nov 1997) |
| population characteristics | <epidemiology> Qualities and characterization of various types of populations within a social or geographic group, with emphasis on demography, health status, and socioeconomic factors. (12 Dec 1998) |
| population control | Includes mechanisms or programs which control the numbers of individuals in a population of humans or animals. (12 Dec 1998) |
| population density | <epidemiology> Number of individuals in a population relative to space. (12 Dec 1998) |
| population diffusion coefficient | <cell biology> Coefficient that describes the tendency of a population of motile cells to diffuse through the environment. Its use presupposes that the cells move in a random walk. (18 Nov 1997) |
| population dynamics | <epidemiology> The pattern of any process, or the interrelationship of phenomena, which affects growth or change within a population. (12 Dec 1998) |
| population genetics | <epidemiology, genetics> The study of genetic influences on the components of cause and effect in the somatic characteristics of populations. (05 Mar 2000) |
| population growth | <epidemiology> Increase, over a specific period of time, in the number of individuals living in a country or region. (12 Dec 1998) |
| population pyramid | <epidemiology> Graphical representation of the age and sex composition of a population, constructed by computing the percentage distribution of the population in each age and sex class. (05 Mar 2000) |
| population surveillance | <epidemiology> Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy. (12 Dec 1998) |
| suburban population | The inhabitants of peripheral or adjacent areas of a city or town. (12 Dec 1998) |
| synchronous cell population | <cell culture> A culture of cells that all divide in synchrony. Particularly useful for certain studies of the cell cycle, cells can be made synchronous by depriving them of essential molecules, which are then restored. Synchronisation breaks down after a few cycles, however, as individual cells have unique division rates. (19 Jan 1998) |
| q in population genetics | The frequency of the less common of two different alternative (allelic) versions of a gene. (the frequency of the more common allele is p). (12 Dec 1998) |
