WebModifier genes are epistatic to the targeted gene, that is, they have a genetic interaction that affects the phenotype. This can be directly at the level of the epistatic gene (e.g., the product of one gene may regulate the expression of another), or it may be indirect (e.g., their products may both participate in a complex pathway). WebThe gene which is suppressed is called hypostatic and the other is the epistatic or inhibiting gene which is also called the suppressing gene. Epistasis can be of the following types. ... Thus in this example, the gene `p' is epistatic to the other colour genes. If the Sorghum is pp, it is brown inspite of other genotypes. The expression of the ...
