Detailed explanation-1: -Complete dominance is a form of dominance in the heterozygous condition wherein the allele that is regarded as dominant completely masks the effect of the allele that is recessive. For instance, for an individual carrying two alleles that are both dominant (e.g. AA), the trait that they represent will be expressed.

Detailed explanation-2: -Mendel’s law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. Rather than both alleles contributing to a phenotype, the dominant allele will be expressed exclusively.

Detailed explanation-3: -Since expression of one allele is masked by the presence of another allele in heterozygous genotype, The masked allele is called as recessive and fully expressed allele is called as a dominant allele.

Detailed explanation-4: -If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

Detailed explanation-5: -The term epistasis describes a certain relationship between genes, where an allele of one gene (e.g., ‘spread’) hides or masks the visible output, or phenotype, of another gene (e.g., pattern).
