Final answer:
A skin graft from the same species is termed an allograft or homograft, which involves transplanting tissue between two genetically distinct individuals within the same species.
Step-by-step explanation:
A skin graft from the same species is called an allograft or a homograft. These types of graft consist of organ or tissue transplantation between two genetically distinct individuals within the same species. An autograft is tissue transplanted from one area on an individual to another area on the same individual, while a xenograft involves tissue from an animal transplanted into a human.
Grafts are subject to immune responses in the recipient that can lead to graft rejection. This immune response is typically against what are known as major histocompatibility complex (MHC) molecules, particularly when these MHC molecules differ between the donor and the recipient.
