In recessive epistasis the recessive alleles at one locus (aa) mask the phenotypic expression of other gene locus (BB, Bb or bb) such epistasis is called recessive epistasis. The alleles of ‘B’ locus express themselves only when epistatic locus ‘A’ has dominant allele like AA or Aa. The phenotypic ratio is 9: 3: 4 (instead of 9:3:3:1).

When two strains of white colored flowers are crossed with each other, the F1 generation is all purple flowered. This means both the genes contribute for the purple color. In absence of even one of them, the color is not produced and the flowers are white. This is an example of which type of epistasis ?
