**6. Equilibrium between mutation and opposing selection**

Deleterious mutants occur by natural selection in the populations. Some deleterious mutants are incorporated into the gene pool of every generation. A particular number of deleterious mutants are also removed in every generation by genetic death. If the elimination is higher in a population than mutation, the frequency of mutants will be minimized. When the numbers are produced to balance the numbers eliminated there will be an equilibrium. If the population will have a greater load of recessive than dominant mutants this will give rise to various diseases and deformities [18]. In a population; the magnitude of deleterious mutants will be determined by the rate of equilibrium of mutants.
