Question

what is the answer?​

Answer 1

After transplantation of liver or other organs, antibody-mediated, hyperacute vasculitic rejection can occur in individuals with preformed antibodies against the donor’s major histocompatibility complex (MHC) class I– encoded antigens. Under most other circumstances, acute allograft rejection is initiated by the large number of recipient T cells that recognize donor alloantigens (mostly those encoded by the highly polymorphic MHC)

Answer 2

All of the cells in a specific organism will have the same number of chromosomes (diploid) except for gametes which have half the number (haploid).
