epistatic gene


epistatic gene
Gene that determines whether or not a trait determined by another gene will be expressed.

For example, when the gene responsible for albinism occurs, the genes that determine skin color are present but not expressed; the gene for albinism is therefore called an epistatic gene.

      in genetics, a gene that determines whether or not a trait will be expressed. The system of genes that determines skin colour in man, for example, is independent of the gene responsible for albinism (lack of pigment) or the development of skin colour. This gene is an epistatic gene. When the albino condition occurs, the genes that determine skin colour are present but not expressed.
