  Recessive epistasis

Recessive epistasis-9:3:4

In Sorghum the dominant gene (P) is accountable for purple color that is dominant over brown (q).

Whenever both the dominant genes (P & Q) are brought altogether either in homozygous or heterozygous situation, the purple color is modified to red.

A cross between purple (PPqq) and brown (ppQQ) outcomes in plants with red color in F1 and whenever F1 heterozygotes are selfed, three types of phenotypic classes are generated in the ratio of 9:3:4 (9 Red, 3 Purple & 4 Brown).

Therefore in this illustration, the gene `p' is epistatic to the other color genes.

When the Sorghum is pp, it is brown in spite of other genotypes. The expression of the color genes is masked when pp is present.

The genes for recessive epistasis are also termed as supplementary genes since the gene P determines the formation of color. The alleles of another gene Q and q specify the color.

When the other gene, P_Q_ takes place, the color of the glume will be red. If P_qq genotype is existed then the color of the glume will be purple. Similarly when pp genotype is existed the color of the glume will be brown.
