  2. MHC proteins from one individual can only be of class I or class II.

  3. Each of the MHC genes has a large number of alleles, but each individual only inherits 2 for each gene.

  4. Once a B cell has matured in the bone marrow, it is limited to two MHC response categories.

 A researcher working on island biogeography mapped how isolation-controlled immigration (I), and area-controlled extinction (E), will act on number of species present on the islands. He forgot to label the size of the islands (small or large) and the location of the islands (near or far) on the graph.
