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.
