Given below, is the result of a complementation test for eight independent mutants (1 to 8).



#Unit 8. Inheritance Biology
  1. two cistrons mutation , 1,3, 4, 6, 7 and 8  represents the one cistron , 2 and 5 represent the second cistron
  2. three cistron mutation will be found  1,3, 4 and 8 represents the one cistron,  6 and 7 represent the second cistron and 2 and 5 represents the third cistron.
  3. the two cistron mutation  1,3,4,6,7 and 8 represent the one cistron while 2 and 5 represent the second cistron in a ordered as  1-3-5-2-4-6-8-7.

  4. All mutations belong to a two cistron, but their order cannot be determined.

b) Sucrose concentration in the apoplast
c) The available number of symporter protein molecules
