If a cell has the partial diploid genotype lacI+ lacO+ lacZ- lacY+ _______________________ lacI- l acO+ lacZ+ lacY- , how will its gene expression in the presence of allolactose?

Fill in the blank(s) with correct word


The lacI+ gene is dominant over lacI-, and the operator is functional. Similarly, the wild-type (+) versions of the lacZ and lacY genes are dominant. So, this construct should function normally in the presence of allolactose.
