A transplant between individuals of different genotypes is known as what?

A transplant between individuals of different genotypes is known as an allograft. This term specifically refers to the transfer of tissue or organs between genetically different members of the same species. In a research context and laboratory animal technology, allografts are commonly used in transplantation studies to assess the immune response and compatibility between different genetic backgrounds.

In contrast, an autograft refers to a transplant where tissue is taken from one part of an individual and placed in another part of the same individual, ensuring complete genetic compatibility. An isograft involves transplantation between genetically identical individuals, such as identical twins, where there is no genetic difference, thus minimizing the risk of rejection. Lastly, a xenograft refers to a transplant between different species, such as animal to human, which introduces different biological challenges and considerations compared to allografts.
