Web30 de ago. de 2016 · Biodiversity is typically observed within a specific location (spatial) and time frame (temporal). Data collected from the spatio-temporal characteristics are defined according to three components: species diversity, ecosystem diversity and genetic diversity. We focus on species diversity for the sake of discussion in this article. WebGenetic diversity is the total number of genetic characteristics in the genetic makeup of a species, it ranges widely from the number of species to differences within species and can be attributed to the span of survival for a species. [1] It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary. csm fort stewart

Neutral genetic diversity consists of genes that do not increase fitness and are not responsible for adaptability. Natural selection does not act on these neutral genes. Adaptive genetic diversity consists of genes that increase fitness and are responsible for adaptability to changes in the environment. Adaptive genes are responsible for ecological, morphological, and behavioral traits. Natural selection acts on adaptive genes which allows the organisms to evolve. The rate of evol… WebIn population genetics, gene flow (also known as gene migration or geneflow and allele flow) is the transfer of genetic material from one population to another.
