In order to analyze how different components of the lac operon work, scientists created special strains of E. coli, called partial diploids. A partial diploid has one full copy of the lac operon in the bacterial chromosome plus another copy of the lac operon in a plasmid. Hence, for the lac operon (and only the lac operon) the bacterial cell is a diploid. Below is one possible genotype of a partial diploid. The genotype written to the left of the slash (/) is that of the lac operon in the bacterial chromosome, and the genotype written to the right of the slash is that of the lac operon in the plasmid. I^-P⁺O⁺Z⁺/ I⁺P^-O⁺Z^-
Under what conditions regarding the presence or absence of lactose (and the actual inducer allolactose that accompanies lactose) would the partial diploid produce functional $\beta$ -galactosidase?
