WebbVariation 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.

"Ultimately, genetic variation is caused by variation in the order of bases in the nucleotides in genes. New technology now allows scientists to directly sequence DNA, which has identified even more genetic variation than was previously detected by protein electrophoresis. Visa mer Genetic variation is the difference in DNA among individuals or the differences between populations. The multiple sources of genetic variation include mutation and genetic recombination. Mutations are the … Visa mer Geographic variation means genetic differences in populations from different locations. This is caused by natural selection or genetic drift. Visa mer Random mutations are the ultimate source of genetic variation. Mutations are likely to be rare, and most mutations are neutral or deleterious, but in some instances, the new alleles can be favored by natural selection. Polyploidy is an example of chromosomal … Visa mer A variety of factors maintain genetic variation in populations. Potentially harmful recessive alleles can be hidden from selection in the Visa mer Genetic variation can be identified at many levels. Identifying genetic variation is possible from observations of phenotypic variation in either quantitative traits (traits that vary continuously and are coded for by many genes (e.g., leg length in dogs)) or discrete traits … Visa mer Genetic variation within a population is commonly measured as the percentage of polymorphic gene loci or the percentage of gene loci in heterozygous individuals. The results can be very useful in understanding the process of adaption to the environment of each … Visa mer Genetic variation can be divided into different forms according to the size and type of genomic variation underpinning genetic change. … Visa mer " - The original source of all genetic variation
