Dec 20, 2016 · Definition. Codominance occurs when two different versions – a.k.a. “alleles” – of the same gene are present in a living thing, and both alleles are expressed separately in different parts of an organism. Instead of one trait being dominant over the other, both traits appear.

Jun 23, 2023 · Codominance Definition. Codominance is a form of inheritance wherein the alleles of a gene pair in a heterozygote are fully expressed. As a result, the phenotype of the offspring is a combination of the phenotype of the parents. Thus, the trait is neither dominant nor recessive.
Nov 18, 2022 · Codominance is a form of inheritance where two alleles of the same gene are expressed roughly equal amounts in an organism. Thus, when alleles for a trait are codominant, both phenotypes are simultaneously displayed.
In this article, we will give you an in-depth explanation of codominance, the difference between incomplete dominance and a codominant relationship, give you a few examples, and a practice problem to try out, so you have a better understanding of this unique relationship.
Type of allelic interaction in which the heterozygote simultaneously expresses traits of both homozygotes.
Sometimes the heterozygotes show a third phenotype due to incomplete dominance or codominance and sometimes there are more than two alleles for a trait in a population. Multiple Alleles and Codominance. Human blood types provide an excellent example of multiple alleles and codominance.
Mar 9, 2024 · In codominance, alleles from both parents are fully expressed, creating a unique phenotype. This genetic phenomenon results in a distinct blending of traits. Codominance is a critical concept in genetics where two different alleles are expressed equally, without one dominating the other.
