HG Evolution II

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

The diagram shows a random change in the population which is:

• Gene flow
• Gene pool
• Genetic drift
• Natural selection

The graph displays periods of abrupt changes after long periods of little change which is:

• Adaptive radiation
• Gradualism
• Punctuated equilibrium
• Extinction

A population of chimpanzees was separated when the forest that they lived in had a section cut down and a town was built. After a long period of time, the chimpanzees came back into contact but were incapable of breeding. Which of the following best describes the process that occurred?

• adaptation
• speciation
• convergent selection
• stabilizing selection

Genetic drift is change in the allele frequency of a population due to...

• random chance
• natural selection
• non-random mating (sexual selection)
• artificial selection
