Environmental and inherited variations
WebHeritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color. Rather, a genetic mutation causes a difference in fur color, which may help that … WebIn this article, we’ll look in more detail at how complex human traits such as height are inherited, as well as how factors like genetic background and environment can influence the phenotype (observable features) produced by a particular genotype (set of gene variants, or alleles).

Genetic variations underlie these changes. Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination).

WebMany studies have investigated variations in specific genes thought to be involved in these traits, comparing athletes with nonathletes. The best-studied genes associated with athletic performance are ACTN3 and ACE. These genes influence the fiber type that makes up muscles, and they have been linked to strength and endurance.

According to Holt, factors such as multiple introductions, habitat heterogeneity, large population size, outbreeding, isolation, polyploidy, and hybridization may all have contributed to these high levels of genetic diversity.
