A bone marrow transplant may not be appropriate from a given donor (Jane) to a given recipient (Janeʹs cousin Bob), even though Jane has previously given blood for one of Bobʹs needed transfusions. Which of the following might account for this?

#Section 2: General Biology

  1. Janeʹs blood type is a match to Bobʹs but her MHC proteins are not.

  2. A blood type match is less stringent than a match required for transplant because blood is more tolerant of change.

  3. For each gene, there is only one blood allele but many tissue alleles.

  4. Janeʹs class II genes are not expressed in bone marrow.
