Question

A student is learning about the Law of Dominance and claims: “If an organism shows a dominant phenotype, it must have a homozygous dominant genotype.” Is this statement correct?

Options

Yes, because only homozygous dominant genotypes can produce a dominant phenotype.

Yes, because the presence of a recessive allele would always change the phenotype.

No, because an organism with a heterozygous genotype can also show a dominant phenotype.

No, because dominant phenotypes are not related to genotypes at all.
