Question

Transplantation between identical twins :

• A. Isograft
• B. Allograft
• C. Autograft
• D. Xenograft

Answer 1

The Correct Option is A

Transplantation between identical twins is referred to as an Isograft. Understanding different types of grafts is crucial in the field of transplant surgery:

• Isograft: This type of graft occurs between genetically identical individuals, such as identical twins. Since their genetic makeup is the same, the recipient's body does not recognize the graft as foreign, thus it typically does not elicit an immune response.
• Allograft: This refers to a graft between two genetically different individuals of the same species. It is the most common type of organ transplant performed today.
• Autograft: This involves the transplantation of tissue from one site to another on the same individual, such as a skin graft.
• Xenograft: This type occurs between individuals of different species, often used experimentally or as a temporary measure.

Given these definitions, the correct answer for transplantation between identical twins is an Isograft.
