Graft of a piece of tissue or organ from one individual to another of the same species

A graft taken from the same person to be used on that person is called an allograft. The term homograph is sometimes used but allograph is usually used.

Allograft and Homograft are used interchangeably in the medical literature to describe a graft originating from a donor whose genetic material is not identical to that of the receiver but they both are of the same species (i.e. humans).

An allograft is a transplant from another member of the same species ( human to human) while and autograft is a transplant from one area of a patient to another (skin graft from upper thigh to foot)

A bone graft is a surgical procedure which is done to repair a bone fracture that is not healing properly or one that is detrimental to a person's life. It repairs the bone and makes it stronger.
