Which graft type involves transplantation within the same individual, such as moving tissue from one site to another?

Explanation:
The key idea is how grafts are categorized by donor–recipient relationship. When tissue is moved from one site to another in the same individual, that is an autograft. Because the donor tissue comes from the same genetic makeup, the immune system usually does not recognize it as foreign, so rejection is unlikely. This makes autografts particularly useful for procedures like relocating skin or bone within the same animal or person. In contrast, an isograft involves genetically identical individuals (such as identical twins), an allograft is between different individuals of the same species, and a xenograft is between different species, all of which carry higher risks of rejection and require different considerations.
