When a heterozygous organism shows characteristics found in each of the associated homozygote states because the different alleles contribute equally to the phenotype,the gene exhibits:
A) Simple dominance
B) Semi-dominance
C) Codominance
D) Incomplete dominance
E) Partial dominance

Question

Quizplus · Accepted Answer

In codominance, both alleles are expressed equally in the phenotype of a heterozygous organism. This means that both the dominant and recessive traits are visible in the individual, rather than blending together or one completely overriding the other. Hence, when a heterozygous organism shows characteristics found in each of the associated homozygote states because the different alleles contribute equally to the phenotype, it is a clear example of codominance.
