Explanation:
Detailed explanation-1: -A third version of this gene, the O allele, codes for a protein that is not functional; it makes no surface molecules at all. Everyone inherits two alleles of the gene, one from each parent. The combination of your two alleles determines your blood type.
Detailed explanation-2: -Blood groups are hereditary. They have a Mendelian pattern, in other words, they are the product of a single gene. The ABO gene has three types of alleles: A, B, and O. The first two, A and B, are codominant, in other words, they dominate equally.
