Genetic diversity is synonymous with genetic variability. It explains why we find distinct individuals and populations within the human species. Each individual has a vast number of genes (around 100,000) that produce their individual traits. Genetic diversity, a tremendous asset for our human heritage, also manifests itself in population distinctions. Populations from different parts of the world have specific characteristics such as skin color, height and the presence or absence of certain enzymes. However, there are some populations that live very far from one another yet share a good number of common traits.
