Imagine You Predict a Particular Frequency for a Genotype,based Upon

Multiple Choice

Imagine you predict a particular frequency for a genotype,based upon detailed knowledge of that genotype frequency in population "X" of a species.Then,using the Hardy-Weinberg model,you find that the observed genotype frequency in a different population,named "Y" of the same species,is not significantly different from what you predicted/expected based on population "X."
Which of the following should you conclude?

A) The particular gene of interest is not undergoing any mechanisms of evolution.
B) Population Y must have diverged,and macroevolution has occurred.
C) Population Y is undergoing mutation,natural selection,genetic drift,and gene flow.
D) The particular gene of interest is evolving through some mechanism.
