Answer 1

The correct answer is Iso graft.

Key Points

Xeno graft:

This is a graft that is transferred from one species to another.
For instance, if tissues were transferred from a pig to a human, that would be considered a xenograft.
This is the least compatible form of graft due to significant differences in tissues among different species, leading to a high chance of graft rejection.

Allo graft:

It is also known as allogenic or homograft, this is a graft transferred between two genetically non-identical members of the same species.
For instance, if tissues were transferred from one human to another human who is not an identical twin, that would be considered an allograft.
Allografts have a moderate chance of graft rejection due to genetic differences between the donor and recipient.

Autograft:

This is a graft transferred within the same individual.
For example, if tissues were moved from one part of a person's body to another part of the same person's body, that would be considered an autograft.
Autografts are the most compatible form of graft as they involve no genetic differences, so there's minimal chance of graft rejection.

Iso graft:

It is also known as isograft or syngeneic graft, this is a graft transferred between two genetically identical individuals, such as identical twins.
Therefore, the correct answer is Iso graft.
Isografts are also highly compatible, with a low risk of graft rejection due to the identical genetic makeup of the donor and recipient.
