B. Gene flow
C. Genetic Drift
D. nonrandom mating
Explanation:
This is for a multiple choice question!! & i just took the test! hope this helps :)
The following events that make it challenging for the Hardy-Weinberg equilibrium to be reached are random mating, Gene flow, and Genetic Drift.
Hardy-Weinberg equilibrium states that the genetic variation remains constant in a particular area from generation to generation if there are no disturbing factors present.
The disturbing factors are genetic drift, mutation, etc.
Thus, the correct options are:
A. random mating
B. Gene flow
C. Genetic Drift
