Detailed explanation-1: -Some genes mask the expression of other genes just as a fully dominant allele masks the expression of its recessive counterpart. A gene that masks the phenotypic effect of another gene is called an epistatic gene; the gene it subordinates is the hypostatic gene.

Detailed explanation-2: -The masked allele is called recessive and the allele that expresses itself is called dominant.

Detailed explanation-3: -Allele refers to variants of the same gene that occur on the same chromosome. An allele is said to be dominant as they override or mask the effect of other variants available for the same gene. If both the alleles are the same, they are said to be homozygous and the character is expressed.

Detailed explanation-4: -The effect of the other allele (the recessive allele) is masked by the dominant allele. Typically, an individual who carries two copies of a dominant allele exhibits the same trait as those who carry only one copy. This contrasts to a recessive trait, which requires that both alleles be present to express the trait.

Detailed explanation-5: -A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent.
