Why is the cheetah gene pool small today?
- Response: multiple bottleneck events
-
After a bottleneck event, the population of rabbits in an area has significantly decreased. A decade later, the population of the rabbits recovers to its original numbers. Which statement is correct about the rabbits?
- Response: They are less likely to survive environmental changes because of the bottleneck event.
-
Question: Facts or data are types of
- Response: evidence.
-
What change is observed in a distribution curve for a trait affected by directional selection?
- Response: It shifts either to the right or to the left.
-
In a population of birds, brightly colored males and very dull males survive best. Which type of selection is this, and what is most likely true about the proportion of males of intermediate coloring?
- Response: Disruptive; males of intermediate coloring make up a small part of the population.
