Question

investigatory projectâ on to study the pedigree chart on blood group of a family

Answer 1

Explanation:

1) Blood group B; Genotype - IB i (2) Blood group = A; Genotype = IA i (3) Blood group - 'AB' → IAIB The allele IA produces glycoprotein A, found on the surface of red blood cells. The allele IB produces glycoprotein B, found on the membrane of red blood cells. When the alleles IA and IB are together, they are equally dominant and both the glycoproteins A and B are produced. The blood group is determined by the presence or absence of one or both the glycoprotein i.e., group A, B and AB, while group O has neither of them.
