If a cell has the partial diploid genotype $\mathrm { lacI } ^ { + } \quad \operatorname { lacO } ^ { - } \operatorname { lac } ^ { + } \quad \operatorname { lac } ^ { + }$
$\overline { l a c I ^ { - } l a c O ^ { - } ~ l a c Z ^ { + } \operatorname { lac } Y ^ { - } }$ ,
how will its gene expression function in the presence of allolactose?
