The genetic makeup of one individual slightly varies from that of the other individual. It becomes essential to determine the occurrence of evolutionary changes in the individuals or a group of individuals (population). Population genetics involves the principles of the transmission genetics applicable to a population. It involves the

study

of the genes and their way of passing on from one generation to the other. It involves both

empirical

and theoretical studies. Hence, we measure and quantify the genetic variation and use the
