A father and mother having A and B blood groups respectively can give birth to a child with O blood group.<\/section>\n
Blood group A can have genotypes I^A I^A or I^A i, and blood group B can have genotypes I^B I^B or I^B i. A child with blood group O has the genotype ii. This genotype can only be formed if both parents contribute an ‘i’ allele.<\/section>\n
If the father has genotype I^A i (Blood Group A) and the mother has genotype I^B i (Blood Group B), their possible offspring genotypes are I^A I^B (AB), I^A i (A), I^B i (B), and ii (O). Therefore, a child with blood group O is a possible outcome if both parents are heterozygous for their respective blood groups.<\/section>\n","protected":false},"excerpt":{"rendered":"
