Genetic Diversity

Genetic Diversity is the mark of a healthy animal species. The entire mechanism of diploid sexual reproduction, universal among mammals, is a biological machine for genetic variation and experimentation. In that way animal species can maintain maximum fitness for survival in the face of environmental change and competition from other living organisms. In order for evolutionary response to change and competition to work efficiently, animal populations must have Genetic Diversity. Without that diversity, the necessary variability cannot occur.
