There existed two varieties of female freshwater Mollusks in which some were streamlined and some had a high bulge. Over the generations, male freshwater Mollusks learned that high bulge favors more production of offspring. So they started preferring to mate with females having high bulge as compared to streamlined. Will this affect Hardy Weinberg Equilibrium in the population?
Correct answer: B. Yes, it will affect the Hardy-Weinberg equilibrium
- A. No, it will not affect the Hardy-Weinberg equilibrium
- B. Yes, it will affect the Hardy-Weinberg equilibrium
- C. It will help to balance the equilibrium
- D. The Hardy-Weinberg equilibrium doesn't apply here
Explanation
The Hardy-Weinberg equilibrium assumes several conditions, one of which is random mating among individuals. When male mollusks develop a preference for females with high bulges, this disrupts random mating, causing changes in allele frequencies over time. This results in a deviation from the expected genotype frequencies predicted by the Hardy-Weinberg principle. Therefore, the preference exhibited by male mollusks affects the equilibrium. The other options are incorrect because they either ignore the importance of random mating or misinterpret the application of the Hardy-Weinberg principle.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
