Based on the genotype of AB blood, the a and b genes are codominant.
Since both A and B antigens are equally prevalent on red blood cells, the A and B genes are related in a codominant manner.
<h3>What is gene?</h3>
A gene is a fundamental building block of heredity and a DNA sequence of nucleotides that codes for the production of a gene product, either RNA or protein.
DNA is initially transcribed into RNA during gene expression.
The RNA may execute a specific function directly or may serve as an intermediary template for a protein.
<h3>What is codominance?</h3>
In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person.
Animals that exhibit codominance include roan cattle and speckled chickens, which have alleles that express both red and white hair as well as both black and white feathers.
