        Inhibiory gene action
        
        Homozygous recessive (bb) condition inhibits phenotypic
        expression of other genes so know as inhibitory gene action
        
        Supplementary action gene
        (9:3:4)
        
        the dominant allele of one of two gene governing
        a character produces phenotypic effect •
        
        Complementary gene
        Interaction
        
        dominant alleles when present together each other are called
        complementary genes and produce a different phenotype.
        
        Duplicate gene interaction
        
        When dominant allele of both gene loci produce
        the same phenotype without cumulative effect.
        
        Polymeric gene action
        
        In Polymeric gene action, two completely dominant genes
        controlling a character produce the same phenotype
        when their dominant alleles are alone.
        
        Masking gene action
        
        When out of two genes, the dominant allele (e.g., A) of one gene masked the activity of allele of another gene (e.g., B) • Then A gene locus is said to be epistatic to the B gene locus •
