Introduction into Genetic Diversity
Genetic diversity provides a species with its form and function. A species genotype refers to their genetic code; what their cells are going to be used for – hair cell, eye cell, muscle cell, etc. A species phonotype refers to the way in which that species gene will be expressed – blonde hair, blue eyes, large muscle tone; which significantly impacts the success of that individuals genes. Without genetic diversity among populations the gene pools would be very limited, which gives way to a rise in mutations and inevitably the end of a species. “Genes regulate body size, shape,

In populations where management does not occur, animal numbers will soon build to levels exceeding range carrying capacity....Balancing deer numbers with the amount of forage available insures maximum body and antler growth in order for more animals to reach their genetic potential” (Wildlife Population Management). They manage the environment in which the deer live, the resources in which the deer consume and the number of deer living through hunting and natural predation – this ensures that the white-tailed deer population does not exceed its carrying capacity. Just as the Texas Parks and Wildlife Commission aids in the population of white-tailed deer, it also monitors the vegetation wildlife across many areas. Although there are some factors they cannot control, like rainfall and temperature, this commission controls the quality of the ecosystems by inspecting the diversity of species, water distribution among populations and grazing patterns of nearby livestock. They also have to keep in mind that the decline of this habitat means the decline of those species that rely on its resources. The commission stated that a healthy herbaceous population consists of high plant diversity, structural diversity (bushes, tall trees, low hanging trees) and good ground cover.
Ex-situ and In-situ Conservation
Since diversity is of great importance to the continued success of all natural biomes, conservation biodiversity is
