Summary Introduction
To explain: The nature and extent of
Introduction: Genetic variations refer to differences among organisms within a given population. It is due to genetic variation that the organisms appear distinct from each other in nature. Genetic variation is a consequence of mutations in the genome, random mating among organisms and due to the cross over that takes place in chromosomes in meiosis.
