allelo-, allel-

One of two or more alternative forms of a gene that occupies the same position on paired chromosomes and controls the same inherited characteristic: An allele can be one of two or more different genes containing specific inheritable characteristics that occupy corresponding positions (loci) on paired chromosomes.

Pertaining to alleles; regarding the production by alternative genes; allelomorphic: In the article Jenny read, certain features of a person's character were influenced by specific allelic combinations.

In genetics, the existence of alleles, or their relationship to one another; allelomorphism: In her book on medicine, Alice read about allelism as being the state of having alleles that are accountable for alternative features, such as smooth or wrinkled seeds in beans.

The once held theory of mutual stimulation of cell growth: Allelocatalysis described the stimulation of growth in a bacterial culture by the addition to it with other cells of the same type.

Pertaining to a chemical interaction between species: An allelochemic mutual action involves release of active chemical substances, such as scents, pheromones, and toxins.

An allelochemic secondary substance is produced by an organism that has the effect of modifying the growth, behavior or population dynamics of other species, often having an inhibitory or regulatory effect.

The second major class of semiochemicals: The term of allelochemicals, relating to allelochemics was first invented by Whittaker in 1970.

Referring to the production of offspring in broods that are entirely of one sex: Mary's mother explained to her daughter that her pet only gave allelogenic birth to babies that were all of one gender.

The production of young animals only of one sex: Alelogeny can occur among some forms of life and procreate only one gender in their broods.

Obsolete, one of several alternative forms of the same gene; allele: Allelomorphs occupy the same relative positions in homologous chromosomes.

Pertaining to or of the nature of allelomorphs: Allelomorphic forms can be either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome, and can control the same character.

The existence, transmission, or inheritance of allelomorphs (one of several alternative forms of a gene).

The use of a protection by a plant, or a discharge of a substance by one plant into the environment, which impedes the germination and growth of other plants: Allelopathy is used by some trees to protect their space by having their roots extract lots of water from the soil, resulting in the fact that other plants cannot survive.

1. The formation, during development, of one organ from more than one embryologic structure.
2. Development of a part from several embryonic structures or tissues.

The frequency distribution of a given set of alleles in a population.

Alleles are variants of a gene that occurs at a given locus.

Physical conditions whereby there are disorders of sensations in which stimuli are perceived as at points on the body that are in fact completely away from the points being stimulated: Mark decided to specialize in the neuroscience area of allesthetics and hoped to work with victims who were not able to determine where feelings of touches were actually located.
