b. Geneticists need to develop better ways to examine traits with different and non-overlapping phenotypic variants.
c. Geneticists need to study how genes work together to produce complex phenotypes in the context of complex environments.
d. Geneticists need to need to develop better ways to measure genetic heritability between different ethnic populations.
Where does variation come from?
a. Mutation
b. Gene flow
c. Founder’s effect
d. Sexual selection
Gene flow is __________________.
a. The movement of genes between generations.
b. The movement of genes between relatives.

a. Habitat modification
b. Reproductive isolation
c. Behavioral adaptation

How do individuals benefit from inclusive fitness?
a. They help others of higher social status, which improves their rank in the group

c. They help other individuals who can be relied upon to return the favor in the future
d. They help others as a way of learning a new skill, which will ultimately help them survive and reproduce
