For an organ transplant,it is an advantage to have an identical twin. Why?

(N/A) Organ transplantation is often the only remedy when vital organs like the heart,liver,or kidney fail to function.
Finding a suitable donor is critical because grafts from animals or unrelated humans are usually rejected by the recipient's immune system.
The body's immune system can distinguish between 'self' and 'non-self' cells. The cell-mediated immune response is primarily responsible for graft rejection.
Tissue matching and histocompatibility are essential for successful transplants,and patients typically require life-long immunosuppressants.
Identical twins share the same genetic makeup and histocompatibility antigens. Therefore,there is no risk of graft rejection,making them the ideal donors.
