adaptation, genetic

adaptation, genetic

any characteristic that improves the chances of an organism transmitting GENES to the next generation (i.e. producing offspring). Such beneficial changes are genetically controlled and can be distinguished from alterations occurring within one generation (see ADAPTATION, PHYSIOLOGICAL) which may not lead to genetic change. Adaptations can affect any level of organization, from cells to whole organisms, and their behaviour. Adaptions are favoured by the process of NATURAL SELECTION.

Further we suggest that its evolution explains seemingly unrelated problems of evolutionary biology: the role of epistasis in adaptation, genetic canalization, developmental constraints, developmental and morphological integration, biological versatility, the evolution of complex adaptations, the biological basis of homology and perhaps the origin of body plans.
