Question

Quizplus · Accepted Answer

A dominant allele will always determine the phenotype, even in the presence of only one copy. In contrast, a recessive allele will only determine the phenotype when two copies are present (homozygous recessive). Codominant alleles will both contribute to the phenotype when present together. Homozygous refers to having two copies of the same allele.
