Two bacterial strains have the same genes for metabolizing a carbohydrate,but one is wild-type for a regulatory inducer while the genetic variant does not produce the inducer.Which of the following statements is CORRECT with regard to the metabolic pathway enzymes?
A) The bacteria have the same phenotype.
B) The bacteria have the same genotype but different phenotypes.

D) The bacteria are phenotypically the same but have different genotypes.
E) The answer cannot be determined from the information provided.

The two bacterial strains have the same genes for metabolizing a carbohydrate, indicating they have the same genotype. However, the presence of the regulatory inducer affects the expression of those genes, leading to different phenotypes. Therefore, the two strains have the same genotype but different phenotypes.
