Genetic drift is a process that causes---

• The genetic makeup of an entire population to disappear
• The genetic makeup of an entire population to be altered
• Organisms to better adapt to their environment
• Organisms to have the same DNA as their parents

Common baboons live on the savanna in breeding groups called troops. While females tend to stay with the troop, younger or less dominant males may leave to join a neighboring troop.
Which of these is a likely outcome of movement by young males? 

• Gene flow occurs between the populations
• relative genotypic frequencies reach a constant state
• Allele frequencies suddenly change

What does being in Hardy-Weinberg equilibrium mean for a population?

• The population is evolving

• The population is not evolving

• Equilibrium would gradually end

• Gene flow would occur but slowly

A population of squirrels that contains a wide variety of phenotypes has a:

• Large amount of genetic variation

• High allele frequency

• Poor chance of surviving habitat change

• Decreased chance of frequent gene flow
