What is most likely to happen to moth populations in the picture shown?

• Light moths--hunted easily, dark moths--population increase

• Dark moths--hunted easily, dark moths--population increase

• Light moths--hunted easily, light moths--population increase

• Lights moths will change their color to match dark moths.

A yellow morph and green morph of an insect lives in the rainforest canopy. You would expect:

• the green population to increase and the yellow to decrease

• both populations should stay the same

• both populations will increase

• the green population to decrease and the yellow to increaseThis is a wrong answer

The _________________ _________________ occurs when there is a reduction in population due to natural disasters, over hunting or disease.

• founder effect

• gene flow

• bottleneck effect

• genetic drift

In which of the following populations would genetic drift be most likely to cause a rapid evolution of the population?

• The human population of India

• A large population of Mexican free-tailed bats living in central Texas

• A geographically isolated population of 5000 green tree frogs

• A small group of 12 cheetahs living in Namibia

Genetic drift occurs most quickly in -

• small populations.

• populations with large genetic variation.

• populations with small genetic variation.

• large populations.

What is gene flow?

• The addition or removal of alleles in a population due to individuals entering or leaving one population for another

• A change in allele frequencies when a new population arises from only a few individuals

• A reduction in population caused by natural disasters, disease, hunting, etc.

• A change in the gene pool due to chance
