What is liver Allotransplantation?

What is liver Allotransplantation?

What is a renal Allotransplantation?

Allotransplantation: The transfer of cells, tissues, or whole organs from one individual to another within the same species. Chronic renal disease: The permanent loss of kidney function.

What is difference between Allotransplantation auto transplantation and xenotransplantation?
