What is the difference between an epistatic gene and a hypostatic gene? an epistatic gene is dominant; a hypostatic gene is recessive. an epistatic gene produces only two phenotypes; a hypostatic gene produces four phenotypes. an epistatic gene masks the effects of another gene; a hypostatic gene is masked by the epistatic gene. an epistatic gene enhances the effects of another gene; a hypostatic gene reduces the effects of another gene. an epistatic gene masks the effects of another gene when the epistatic gene has one or more dominant alleles; a hypostatic gene masks the effects of another gene when the hypostatic gene has two recessive alleles?
