  • strongRecessive/strong alleles at one locus (aa) mask the phenotypic expression of other gene locus (BB, Bb or bb) such strongepistasis/strong is called strongrecessive epistasis/strong. The alleles of 'B' locus express themselves only when strongepistatic/strong locus 'A' has dominant allele like AA or Aa. The phenotypic ratio is 9: 3: 4.
