How Codominant Inheritance Patterns?

In codominant inheritance , two different versions (alleles) of a gene are expressed, and each version makes a slightly different protein. Both alleles influence the genetic trait or determine the characteristics of the genetic condition.

How does codominance inheritance pattern exist?

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.

How codominant inheritance patterns differ from dominant recessive inheritance patterns?

With codominance, there are two not one dominant alleles and each one dominates over the recessive allele but not each other. With incomplete dominance there is neither a dominant nor recessive allele but two different homozygous individuals. When a heterozygous condition exists both alleles are expressed.
