- 3. Multiple Choice
Which of the following is true of genetic drift?
It is necessary in order for a population to be in equilibrium.
It can increase genetic diversity, and it amplifies more in a large population.
It can decrease genetic diversity, and it amplifies more in a small population.
It allows large species to have more breeding opportunities.
- 4. Multiple Choice
Which of the following best illustrates natural selection?
Traits that are favored are more likely to appear in the future generation, leading to an overall change in the population.
Organisms learn to adapt, leading to an overall change in the population.
Traits are acquired get passed down to the next generations, leading to an overall change in the population.
