Genetic variability information


Genetic variability is either the presence of, or the generation of, genetic differences. It is defined as "the formation of individuals differing in genotype, or the presence of genotypically different individuals, in contrast to environmentally induced differences which, as a rule, cause only temporary, nonheritable changes of the phenotype."[1] Genetic variability in a population promotes biodiversity, as it ensures that no two living things are exactly alike.[2] While many factors can cause genetic variability, some factors can also decrease genetic variability.
