For the following lac operon partial diploid genotypes, indicate with a (+) or (- ) whether enzymatic activity would be detected for -Galactosidase and/or Permease when lactose is absent and when lactose is present. Solution is given below could you explain how to get them?

A.) I+ P+ Oc Z+ Y- / Is P+ O+ Z- Y+

B.) I- P+ O+ Z+ Y+ / I+ P+ O+ Z+ Y-

C.) I+ P- Oc Z+ Y- / I+ P+ O+ Z- Y+

D.) I- P+ Oc Z+ Y- / I+ P+ O+ Z- Y+

E.) Is P- Oc Z+ Y+ / I+ P+ O+ Z+ Y-

F.) I+ P- O+ Z+ Y- / I- P+ OC Z- Y+
