Person with blood group AB is considered as universal recipient because he has:
Correct answer: A. Both A and B antigens on RBC but no antibodies in the plasma
- A. Both A and B antigens on RBC but no antibodies in the plasma
- B. Both A and B antibodies in the plasma
- C. No antigen on RBC and no antibody in the plasma
- D. Both A and B antigens in the plasma but no antibodies
Explanation
A person with blood group AB has both A and B antigens on the surface of their red blood cells (RBCs). Antigens are substances that can trigger an immune response in the body. In this case, since the person has both A and B antigens, their immune system does not produce antibodies against these antigens. As a result, when receiving blood transfusions, the person's plasma will not contain antibodies that would attack and destroy the transfused blood cells. Therefore, a person with blood group AB is considered a universal recipient because they can receive blood from individuals with blood groups A, B, AB, and O without an immune response.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
