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 and ...


ADVERTISEMENTS: Let us make in-depth study of the meaning, types and importance of variations in different organisms. Variations mean the differences (morphological, physiological, cytological and behaviouristic) amongst the individuals of the same species and the offspring of the same parents. They are found in all the characters and in every conceivable direction.


Variation among organisms This refers to differences among organisms of the same species due to the differences in the genes they inherit and the environment they survive in. Type of Variation: There are two main types of variation namely, Environmental variation and genetic variation. Environmental variation This refers to differences amongst organisms of the same…


Video of presentation for OCR Biology Module " Foundations in Biology, section 4.2.2, discussing the different types of variation.


Genetic variation is the variation in alleles and genes, both within and among populations. Think of a population as a family unit. Think of a population as a family unit.


Biology Assignment Help, Types of variations, Types of Variations - Somatogenic and Blastogenic Variation Changes in somatic parts of the body are somatic variations e.g. wrestler's muscle, circumcised penis of muslims, etc., not inheritable, hence have no role in evolution. Blast


variation /var·i·a·tion/ (var″e-a´shun) the act or process of changing; in genetics, deviation in characters in an individual from the group to which it belongs or deviation in characters of the offspring from those of its parents.


Types of variation. Variation can either be continuous or discontinuous. Discontinuous variation describes variation in which different alleles of one gene have a large effect on the phenotype of the organism.With this type of variation, individuals can be grouped into distinct classes.


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 ...
