Ten individuals of two inbred strains of mice, A and B, are fed identical diets. All have normal blood sugar as adults. The same mice are then fed diets high in sugar. Mice from strain B develop diabetes, but mice from strain A do not. Diabetes in strain B mice results from:
A)the interaction of their diet with their genotype.
B)their genotypes, which are different from strain A mice.
C)their diets, which are different from strain A mice.
D)their norm of reaction to sugar in their diets.
E)None of the other answer choices is correct.

Question

The fact that mice from strain B develop diabetes while mice from strain A do not suggests that the development of diabetes is influenced by genetics, as the only difference between the two strains is their genotype. However, the fact that the disease only develops when the high sugar diet is introduced, suggests that diet also plays a role in the development of diabetes, making the answer A the most likely explanation as it states that diabetes in strain B mice results from the interaction of their diet with their genotype.
