Final answer:

Qualitative and quantitative traits differ in genetic control and environmental influence. The environment has a minimal effect on genes of qualitative traits but significantly impacts quantitative traits.


Explanation:

Qualitative traits are controlled by single or few genes, with minimal influence from the environment, leading to distinct categories of phenotypes. On the other hand, quantitative traits are controlled by several genes, show continuous variation in phenotypes, and are significantly impacted by the environment.

In the context of the given options, the statement that the environment has little or no effect on the genes of a qualitative trait (Option D) is not correct. The environment indeed plays a minimal role in qualitative traits, but it has a substantial impact on quantitative traits.
