Question

A. Isograft
B. Xenograft
C. Allograft
D. Autograft

Answer 1

Hint: As we know that organ transplantation is a procedure used in the medical field that involves the removal of an organ from one individual usually referred to as donor and placing it in the body of the recipient so as to replace a damaged organ.

Complete answer:
We know that a person with damaged or missing organs or tissue can get it from another individual. Organ transplantation or grafting are such procedures that involve the removal of an organ from one individual usually referred to as donor and placing it in the body of the recipient so as to replace a damaged organ or even any missing organs and same is done with the case of tissues.
There are many types of organs transplants which includes: Isografts, Xenografts, Allografts and Autografts.
Let us discuss these terms one by one. First is Autograft which are the tissue transplants that are performed in the same individual where a tissue is taken from a place where it is less needed and can be placed where it is desperately needed.
Next one is Allografts which is a transplant of organs or a tissue from a genetically distinct individual to another individual of the same species. Most human transplants fall into this category.
Then comes Xenograft and these are those transplants which are performed between two individuals of different species like an animal graft can be transplanted into a human.
Lastly we have Isograft which is a variant of allografts where tissues can be transplanted between identical twins only.
Therefore from the above explanation we can say that the father’s kidney can be categorised under Allograft transplantation.

Hence, the correct answer is (C).

Note:
Remember that not all transplants are successful, sometimes organs or tissues are rejected by the recipient’s body due to the detection of different antigens on the cells of the organ or due to the mismatching reasons which triggers a blood transfusion reaction or commonly called transplant rejection.
