The correct term for tissue transplanted from one individual to another of the same species but with a different genotype is "allograft." An allograft involves the transfer of cells, tissues, or organs from one organism to another of the same species that is not genetically identical. This is important in medical contexts, especially in organ transplantation, where a patient may receive a kidney or heart from a donor who is not genetically identical. While the recipient's immune system may recognize the transplanted tissue as foreign, immunosuppressive therapies are commonly used to help prevent rejection of the graft. Other types of grafts include autografts, where tissue is transplanted from one part of a person's body to another, and isografts, where the donor and recipient are genetically identical (such as identical twins). Xenografts refer to transplants between different species, such as from pigs to humans. Each of these terms describes distinct transplant scenarios crucial for understanding the compatibility and potential rejection of grafts in medical procedures.
