What is codominance?
What is codominance?
A condition in which neither of two alleles of a gene is dominant or recessive.
What are codominant alleles?
What are codominant alleles?
Pairs of alleles that both affect the phenotype when present in a heterozygote.
What does the expression of alleles result in?
What does the expression of alleles result in?
Different phenotype than either homozygous individual.
Study Notes
Codominance Overview
- Codominance occurs when two alleles of a gene are expressed equally, neither dominating the other.
- This genetic scenario results in a phenotype that is a combination of the traits associated with both alleles.
Codominant Alleles
- Codominant alleles are pairs of alleles that manifest distinct traits in a heterozygous individual.
- In the presence of both alleles, both traits can be observed simultaneously in the organism's phenotype.
Phenotypic Expression
- The phenotype of a heterozygote exhibiting codominance will differ from that of homozygous individuals.
- This results in a unique expression of traits not found in either of the homozygous forms.

Description
Explore the concept of codominance in genetics, where two alleles are expressed equally in a phenotype. This quiz covers codominant alleles, their expression in heterozygous individuals, and how this differs from homozygous traits. Test your knowledge on this fascinating genetic phenomenon!
