    The phenomenon of the interaction between nonallelic

    genes at two or more loci resulting in one gene masking the phenotypic expression of another gene, is known as:
    A linkage Correct Answer Incorrect Answer
    B complete inheritance Correct Answer Incorrect Answer
    C epistasis Correct Answer Incorrect Answer
    D incomplete inheritance Correct Answer Incorrect Answer

    Solution

    Epistasis is the interaction between genes at different loci, where one gene can mask or modify the expression of another gene, affecting phenotypic outcomes. It is a form of gene interaction different from simple dominance or linkage.
