Hint: A blood type (also known as a blood group) is a blood grouping based on the appearance and absence on the surface of red blood cells of antibodies and hereditary antigenic substances (RBCs). Depending on the blood group system, these antigens can be proteins, carbohydrates, glycoproteins, or glycolipids. Any of these antigens are also found on the surface of the different tissues of other types of cells.
Complete answer:
Blood forms are inherited by both parents and reflect achievements. The two most relevant blood group systems are ABO and Rh. Two antigens and two receptors present in human blood are active in the ABO blood group scheme. Antigen A and antigen B are the two antigens. Antibody A and antibody B are the two antibodies. The red blood cells and the antibodies in the serum produce antigens. All human beings can be divided into 4 categories concerning the antigen properties of the blood: those with antigen A (group A), those with antigen B (group B), those with both antigen A and B (group AB) and those with neither antigen (group O).
If a child has an “O” blood group, then both mother and father should have one allele as O because O is a recessive trait in blood and if the blood group of a person is O, then it means that the blood group should be homozygous. Therefore, according to the question, a father with one allele like 'B' should have one allele like 'O'.
Hence, the correct answer is option (D).
Note: As of 2019, the International Society of Blood Transfusion (ISBT) acknowledges a total of 38 human blood group systems. They specify the type of the blood of someone (A, B, AB, and O, with $ + $, $ - $or null denoting RhD status) for blood transfusion suitability.
