Genetic variability

<p>
Genetic variability is either the presence of, or the generation of, genetic differences. It is defined as "the formation of individuals differing in <a href="/facts/Genotype/MlzK1Mfz">genotype</a>, or the presence of genotypically different individuals, in contrast to environmentally induced differences which, as a rule, cause only temporary, nonheritable changes of the <a href="/facts/Phenotype/vxWXKGLj">phenotype</a>." Genetic variability in a <a href="/facts/Population/ArxshNuB">population</a> promotes <a href="/facts/Biodiversity/GruakEzs">biodiversity</a>, as it ensures that no two living things are exactly alike. While many factors can cause genetic variability, some factors can also decrease genetic variability.
</p><p>Species variability refers to the observable differences within a species, often encompassing morphological, physiological, behavioral, or phenotypic traits. While genetic variability contributes to species variability, external factors like the environment or developmental conditions can also influence the traits expressed.
