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?
