Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning ...


variation. ecophenotypic variation (see ECOPHENOTYPE caused by local factors, as opposed to genetic factors, in an organism. any differences (both genotypic and phenotypic) between individuals in a population or between parents and their offspring. see GENETIC VARIABILITY.


Genetic Variation Definition. Genetic variation can be described as the differences between organisms caused by alternate forms of DNA. Genetic variation in combination with environmental variation causes the total phenotypic variation seen in a population.The phenotypic variation is what is seen by the observer; the height of a plant for instance. The environmental variation is the difference ...


Variation, in general sense, pertains to the deviations or divergences in a set or a group. In biology, variation refers to the differences or deviations (e.g. in structure, form, function) from the recognized norm or standard. []

variation, in biology: see Darwinism Darwinism, concept of evolution developed in the mid-19th cent. by Charles Robert Darwin. Darwin's meticulously documented observations led him to question the then current belief in special creation of each species.


Adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation over several generations. Organisms are adapted to their environments in a variety of ways, such as in their structure, physiology, and genetics.


Genetic variation can be defined as the genetic makeup of organisms within a population change.Genes are inherited segments of DNA that contain codes for the production of proteins. Genes exists in alternate versions, or alleles that determine distinct traits that can be passed on from parents to offspring.
