Express the genotype of AB blood group?
Blood group is a genetically inherited trait. ABO blood groups are controlled by gene I. The gene I has three alleles IA, IB and i. Blood group is determined by these three factors. 4 types of blood group can be formed by these alleles and they are:
1. Blood group A in which the allelic combination is either IAIA or IAi.
2. Blood group B in which the allelic combination is either IB IB or IBi.
3. Blood group AB in which the allelic combination is IAIB.
4. Blood group O in which the allelic combination is ii. An individual inherits one allele from father and other from the mother.
