Undersea landslides can disrupt marine habitats by burying organisms that live on the ocean floor. The graph above shows the size of a population of a certain organism that lives on the ocean floor. The population was affected by a recent landslide at the time indicated on the graph. Which of the following best predicts how the population will be affected by the landslide?
A) The surviving organisms will evolve into a new species.
B) The reduced population will likely have allelic frequencies that are different from the initial population.
C) The population will adapt to deeper waters to avoid future landslides.
D) The reduced population will have a greater number of different genes than the initial population.
Ans: B) The reduced population will likely have allelic frequencies that are different from the initial population.
