Codominance — Overview & Examples
Read this topicExplanations 5
- What Is a Codominant Trait? Codominance occurs when two heterozygous alleles are fully expressed. Neither allele can dominate, so they both show up, but they do not blend. The p…

- What Is Codominance? Unlike Mendelian patterns of inheritance, codominance can create three distinct phenotypes using just two alleles. For a codominant trait, a heterozygous or…

- What Is a Human Example of a Codominant Trait? In codominance, two alleles are equally expressed in the phenotype of an organism. We can easily see this by looking at blood type…
