Question

What is co-dominance? Explain with example

Answer 1

Co Dominance is expression of all alleles in a gene. The best example for that is human blood grouping. O group has no sugar crystals on the RBC while A has Ia type of sugar and Butter has Ib type of sugar. Thus the person having AB blood group has both Ia and Ib type of sugars on the surface of RBCs.

Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
