Selective breeding utilizes the natural variations in traits that exist among members of any population. differences between individual people in a family or population, or at the population level, i.e. Get exclusive access to content from our 1768 First Edition with your subscription.
It is the presence of different individuals due to their genotypic constitution derived from genes, chromosomal recombination, linkage, etc. 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.
Variation is the differences between individuals within a species.
differences between organisms caused by alternate forms of DNA
Variation can, therefore, be measured at the individual level, i.e. The gene pool is the sum total of all the genes and combinations of genes that occur in a population of organisms of the same species.
differences between populations living in different regions.Explore DNA structure/function, chromosomes, genes, and traits on this vid and find out how this relates to heredity. Organisms are adapted to their environments in a variety of ways, such as in their structure, physiology, and genetics. Definition noun, plural: genetic variations Variations of genomes between members of species, or between groups of species thriving in different parts of the world as a result of genetic mutation Supplement In genetics, variation refers to an individual with characteristics different from the others of the same kind.

The extent or degree to which something varies: a variation of ten pounds in weight. Breeding progress requires understanding the two sources of variation: genetics and environment. 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. 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).
