| Genetic problems involving codominance are similar to those of incomplete dominance. |
| Some alleles do not have complete dominance and instead have incomplete dominance by expressing an intermediate phenotype, or codominance by expressing both alleles at once. |
| The key difference between simple dominance and codominance is that in codominance the heterozygote exhibits a distinct phenotype. |
| The fact that codominance is the rule in the style suggests that the active protein is a monomeric protein. |
| The hypothesis of codominance is accepted rather generally even though that of simple dominance is an alternative that has not been entirely disproved. |
| Dominance and codominance are preponderant but there is little competitive interaction. |
