Detailed explanation-1: -Individuals inherit two versions of each gene, known as alleles, from each parent. In the case of a dominant trait, only one copy of the dominant allele is required to express the trait. The effect of the other allele (the recessive allele) is masked by the dominant allele.
Detailed explanation-2: -In contrast to recessively inherited traits, some alleles are dominant. With a dominant trait, an individual will express the associated phenotype even with just one copy of the allele for the trait.
Detailed explanation-3: -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-4: -The trait of the weaker gene is “hidden” or does not show up and is called the recessive gene. The trait that was always visible in the offspring was considered to be the stronger of the two.
