D) I, II and IV
Correct Answer: A
Solution :
[a] Since, genes A and B are more close than genes A and C, therefore, gene A has to be present before genes B and C with gene B present in between genes A and C. Other options are incorrect and can be corrected as Gene C is not between genes A and B. More crosses have occurred between A and C than A and B.
