Definition

Genetic diversity is a fundamental source of biodiversity which has been defined by different authors as “any measure that quantifies the magnitude of genetic variability within a population” (Hughes et al. 2008) or “the very makeup of the variation of organisms and species on Earth” (Elliott 2002). According to Ennos et al. (2000), genetic diversity presents “the range and sum of genetic variation within a population or populations,” where the term diversity, which simply means the state of displaying dissimilarities, differences, or variety, has acquired an extended meaning which signifies the sum of the variation.

Each individual species is made up of individuals that possess their genes, which are the source of its own unique features (genes are responsible for both the similarities and the differences between organisms). A species may have different populations, each having different...
