#Unit 8. Inheritance Biology

  1. All mutations belong to a single cistron, but their order cannot be determined

  2. The mutations can be ordered in a single cistron as A-C-E-B-D-F-H-G
  3. There are two cistrons, mutations A, C, E, G and H represents one cistron, B, D, F and G represent the second cistron.
  4. There are three cistrons, mutations A, C, E and H represents one cistron, B, D and F represent the second cistron and G represents the third cistron.
