<P> Forward genetics is the approach of determining the genetic basis responsible for a phenotype . This was initially done by using naturally occurring mutations or inducing mutants with radiation , chemicals , or insertional mutagenesis ( e.g. transposable elements ) . Subsequent breeding takes place , mutant individuals are isolated , and then the gene is mapped . Forward genetics can be thought of as a counter to reverse genetics , which determines the function of a gene by analyzing the phenotypic effects of altered DNA sequences . Mutant phenotypes are often observed long before having any idea which gene is responsible , which can lead to genes being named after their mutant phenotype ( e.g. Drosophila rosy gene which is named after the eye colour in mutants ) . </P>
