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). http://api.3m.com/recessive+epistasis+ratio
