Question

Why human with heterozygous genotype will have the dominant phenotype?

Answer 1

A human with heterozygous genotype can have a dominant phenotype if one of the alleles complete mask the effects of the other.

• Heterozygous genotype involves two different alleles, unlike homzygous genotypes in which the alleles are the same.
• When the two alleles of an heterozygous genotype exert equal effects on one another, they are said to be codominant.
• When one of the alleles of an heterozygous genotype incompletely exert its effects on the other allele, it is said to be incomplete dominance.
• When one of the alleles complete dominates and masks the effects of the other allele, it is said to be dominant.

Hence, a dominant allele will always produce a dominant phenotype even if the genotype of the organism is heterozygous.
