Variation is the difference among member of population or members of different population. Types of variation (1) morphological or physical variation: this is concern with the physical appearance of an organism. In animal such morphological includes: height; body weight; finger prints; colour of skin, eye and hair; sexes in male and female.
The biology of human variation within every species, a species defined as two living beings which are able to breed and reproduce together, there is individual variation. No two animals, or humans for that matter, are ever exactly alike. Each person is built a little differently and has different influences from their environment.

Types and examples of variation in biology: continuous variation: it manifest by small phenotypic differences, generally quantitative, that affects all the organs discontinuous variation: it is any morphological or functional variation that appears suddenly in one or several.
Variation in a characteristic that is a result of genetic information from the parents is called inherited variation. Children usually look a little like their father, and a little like their.
4 genetic information, variation and relationships between organisms. Biological diversity – biodiversity – is reflected in the vast number of species of organisms,.
Evolution begins with the inheritance of new genetic variation. Variation describes differences in the genetic make-up between individuals within a species.
7 jan 2014 finally, genetic and phenotypic variation may promote population implications for conservation biology and (re)introduction programs.
We argue that model organism biology would benefit from incor- porating natural variation, both to capture how well laboratory lines exemplify the species they.
26 feb 2021 in genetics, variation refers to an individual that possesses characteristics different from the others of the same kind.
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 is the differences between individuals within a species.
They belong to the same species your friends and classmates may have different eye colour and hair colour.
The extent or degree to which something varies: a variation of ten pounds in weight. Biology the existence within a species or other group of organisms of differences in form, function, or behavior, especially when hereditary.
Genetic variation occurs mainly through dna mutation, gene flow (movement of genes from one population to another) and sexual reproduction. Since environments are unstable, populations that are genetically variable will be able to adapt to changing situations better than those that do not contain genetic variations.
Biological ideas and processes relating to sources of variation within a gene pool mutation as a source of new alleles.

Variation describes differences in the genetic make-up between individuals within a species. Variation can exist in all cells of the body, but is only passed on to the next generation when it is present in the gametes. In this way, genetic variation can influence future generations and alter the genetic pool of the population.

Variation - (biology) an organism that has characteristics resulting from chromosomal alteration mutant mutation sport organism being - a living thing that has (or can develop) the ability to act or function independently.
Individuals in a population are usually similar to each other, but not identical.
In biology, polymorphism is the occurrence of two or more clearly different morphs or forms, due to having more than one possible variation for this gene, it is termed 'polymorphism'.
