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-for the partial diploid genotype shown here, determine whether functional β-galactosidase is synthesized in the absence and in the presence of lactose (and the accompanying allolactose that is the actual inducer).
