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.

Explanation:
In the expanse of the space-time continuum of the universe there are many celestial bodies from stars to planets that all formed at different times hence have different ages and are at different stages of formation.
Studying other planets helps reveal alot about our own planet, its history and its formation. By observing younger earth-like planets, scientists could understand how the earth looked like in its younger years and how it was formed.
