b. The two bacterial strains have different phenotypes.
Explanation:
In genetics, the trait that is expressed is often referred to as the dominant trait and it can also be expresssed phenotypically.
Since one of the bacteria produces the inducer, it therefore means that bacteria has the dominant strain for the regulatory inducer while the other bacteria might have the strain but since it is not expressed phenotypically, it is as a result not dominant.
Phenotype refers to the physical appearance of an organism as a result of the interaction of its genes with the environment. Examples of phenotypic expresssions are hair colour, skin colour, height, etc.
