A landslide has isolated a part of the cicada population from the main population. After a few generations, the new generations of cicadas exhibited dramatic gene differences from the old one.
Which mechanism is the most likely cause of these differences?
OA
bottleneck effect
OB.
disruptive selection
OC. migration, or gene flow

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.

i think it is d. objects resist changes in their state of motion.
