Grafting done between genetically different individuals of the same species is -

o Based on the donor, the graft may be > 1. Autograft (autogenic graft): Graft from self. 2. Isograft (syngraft): Graft from a genetically unrelated member of same species. 4. Xenograft (heterograft): Graft from different species. ÿ Orthoptic graft ÿ Hetera topic graft → Graft applied in anatomically normal site eg. skin graft. → Graft applied in anatomically abnormal site. o After organ transplantation (graft) two types of reaction can occur 1. Host versus graft reaction: It refers to the reaction of the host to grafted (transplanted) organ, i.e. graft rejection  2. Graft versus host (GVH) reaction: It refers to the immune response of graft against the antigens of the host, e.g. Runt disease in animals.
