Webdiversity is substantially lower than that of many other species, including our nearest evolutionary relative, the chimpanzee. Genetic diversity is a function of a population's "age" (i.e., the amount of time during which mutations accumulate to generate diversity) and its size. Our genetic homogeneity implies that anatomically modern humans arose WebNov 5, 2024 · 1. Introduction. Genetic diversity is a crucial characteristic of any population or species, as genes coding for causative traits are tools by which the populations are equipped to adapt to environmental challenges [1, 2, 3].High genetic diversity, therefore, is assumed an advantage or even a must, for species survival when environmental factors …
WebGenetic variation is the raw material of evolution. Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction. For example, if a population is exposed to a new disease, selection will act on genes for resistance to the disease if they exist WebThese results indicate that the genetic diversity of the largemouth bass in China was dramatically lower than that of the wild population in America.
