There existed two varieties of Female Fresh Water Mollusks in which some were streamlined and some had high bulge. Over the generations, Male Fresh Water 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 effect Hardy Weinberg equilibrium in the population ?

A. No, it will not affect Hardy Weinberg equilibrium B. Yes, it will affect Hardy Weinberg equilibrium C. It will help to balance equilibrium D. Hardy Weinberg equilibrium doesn't apply here

266

A. The balance of the genetic equilibrium of that population B. No affect to the genetic equilibrium of that population C. Change in the genetic equilibrium of that population D. Genetic equilibrium doesn't apply in that population

267

Genetic equilibrium is a:

A. Change of allele and gene frequency in a population B. Stability of allele and gene quantity in a population C. Change of allele and gene number in a population D. Stability of allele and gene frequency in a population
