Type of graft, best suited for renal transplantation

Isograft is the graft of tissue between two individuals who are genetically identical i:e, monozygotic twins. Transplant rejection between two such individuals viually never occurs. As monozygotic twins have the same histocompatibility complex, there is very rare chance of rejection of transplanted tissue by the adaptive immune system.
