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: -Which of the following refers to a complete dominant cross? One allele completely dominates over the other. The two alleles are equally seen in the heterozygous genotype.

Detailed explanation-3: -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-4: -The flowers on Mendel’s pea plant are an example of complete dominance, or when the dominant allele completely covers up the recessive allele.

Detailed explanation-5: -One allele is NOT always completely dominant over another allele. Sometimes an individual has a phenotype between the two parents because one allele is not dominant over another. This pattern of inheritance is called incomplete dominance. For example, snapdragon flowers show incomplete dominance.
