In this article we discuss about the expression of mutations. The expression of mutation can be observed only when there occurs a detectable and altered phenotype. If a mutation occurs from a most prevalent wild type to a mutant form, it is called forward mutation. In forward mutation, a second mutation may take place resulting […]
