4. Which of the following describes how a large mouse population with high genetic diversity will most likely be affected by a sudden, significant environmental change?
(SB6d)
A. All of the individuals within the population will reproduce at a higher rate, leading
to a decrease in genetic diversity.
B. New traits will arise as a result of new selective pressures in the environment,
leading to an increase in genetic diversity.
C. Only those individuals best adapted to the new environment will survive and
reproduce, leading to a decrease in genetic diversity.
D. Only some individuals will develop traits to help them survive in the new
environment, leading to an increase in genetic diversity.
