Allograft\\\n\\\n**Explanation:**\n\n- An “isograft“ is performed between genetically identical individuals (i.e. monozygotic twins)**.**\n- A “heterograft” is not a word that is used in transplantation immunology.\n- A “xenograft” is a transplant that is performed across species.\n- An “autograft”  is a transplant from one location in the body to another.\n- An allograft is a transplant between two members of the same species who are not genetically identical. So option **“e”** is the right answer.\n\n66.c. Serum sickness\\\n67.a. HLA\\\n68.e. B cell\\\n69.a. SCID\\\n70.d. CD4\n\n## Answers to Bonus Questions\n\nBonus 1.c.
