allelo-, allel-

1. One of two or more alternative forms of a gene, occupying the same position on paired chromosomes and controlling the same inherited characteristic.
2. One of two or more different genes containing specific inheritable characteristics that occupy corresponding positions (loci) on paired chromosomes.

Pertaining to alleles; produced by alternative genes.

The existence of alleles, or their relationship to one another.

The once held theory of mutual stimulation of cells to growth, or stimulation of growth in a bacterial culture by the addition to it of other cells of the same type.

1. Chemical interactions between species, involving release of active chemical substances; such as, scents, pheromones, and toxins.
2. A secondary substance 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.

Producing offspring in broods that are entirely of one sex.

One of several alternative forms of the same gene, occupying the same relative positions in homologous chromosomes.

Pertaining to or of the nature of allelomorphs; either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome and that 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.

1. Regeneration whereby one part is transformed into another by reorganization of tissue fragments rather than by cell proliferation.
2. Transformation of one part into another in the regeneration of parts.
3. A gradual growth or development into a particular form.
