Q: What is the transplantation of graft between genetically identical individuals?
  • A. Autograft
  • B. Isograft
  • C. Allograft
  • D. Xenograft
Correct Answer: Option B - Isograft is a graft of tissue between two individuals who are genetically identical (i.e. monozygotic twins). Transplant rejection between two such individuals virtually never occurs, making isografts particularly relevant to organ transplantation patients with organs from their identical twins are incredibly likely to receive the organs favorably and survive.
