Detailed explanation-1: -Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. 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-2: -In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

Detailed explanation-3: -Dominant alleles express a trait, even if there is only one copy. Recessive alleles can only express themselves if there are two copies-one from each parent.

Detailed explanation-4: -If the alleles are different, the individual is heterozygous.

Detailed explanation-5: -Incomplete Dominance, Codominance, Polygenic Traits, and Epistasis!
