Answer

To solve the question "Blood transfusion is `………..` grafting," we need to understand the different types of grafting and identify which one applies to blood transfusion.

### Step-by-Step Solution:

1. **Understand Grafting**: Grafting refers to the process of transplanting tissues or organs from one site to another. It can involve the same individual or different individuals.

2. **Identify Types of Grafting**:
- **Autografting**: This involves taking tissue from one part of an individual's body and transplanting it to another part of the same individual. For example, skin grafts taken from one area of a patient’s body and placed on another area.
- **Isografting**: This is the grafting between genetically identical individuals, such as monozygotic twins.
- **Homografting**: This involves grafting tissues from one individual to another individual of the same species. For example, blood transfusion from one human to another.
- **Xenografting**: This is the transplantation of tissues from one species to another, such as from animals to humans.

3. **Apply to Blood Transfusion**: Blood transfusion involves transferring blood from one person (donor) to another person (recipient) of the same species (humans). Therefore, it fits the definition of homografting.

4. **Conclusion**: Based on the definitions and the nature of blood transfusion, we conclude that blood transfusion is a type of homografting.

### Final Answer:
Blood transfusion is **homografting**.
