A beetle population consists of four greena nd two red beetles that live on a specific tree. during a thunderstorm, high winds blow away the red beetles off the tree and the green beetles are left.

The reason for this change in allele frequency of the beetles is...

C. Sexual selection: green is the preferred color for female beetles choosing a mate

D. Aritificial selection: scientists are purposefully breeding only green beetles
