There are 2 herds of Caribou in Northwestern Montana, one male Caribou strays from one herd to mate with a female in the other herd. What mechanism of evolution is this?

• Gene Flow

• Genetic Drift

• Population Drift

• Divergent Evolution

In a forest a large fire broke out that destroyed much of the area. There were 2 large populations of rabbits, one with brown fur and the other with white fur. After the fire the there were hardly any of the rabbits with white fur left. What mechanism of evolution is at work here?

• Gene Flow

• Genetic drift

• Allele frequency

• Natural selection

Which of the following would be considered genetic drift?

Select all that apply.

• A female deer leaves her herd to join a separate large herd

• A few spotted rabbits leave a large population of rabbits and start a new population of their own in a different place

• Following a hurricane, a species of lizard was thought to be extinct until a small pregnant female was found alive.

• The black robin was hunted until only 5 individuals were left. Through careful conservation efforts, the population is now over 250 birds.,

• Following a hurricane, it was discovered that only one lizard survived.

Which of the following represents a gene pool?

• 
• 

When Arizona's Grand Canyon formed, squirrels and other small mammals that had once been part of a single population could no longer contact and reproduce with each other across this new geographic barrier. They can no longer interbreed. This is an example of...

• founder effect

• speciation

• gene flow

• coevolution

The sugar flying and the flying squirrel are distantly related, but share many characteristics. This is an example of?

• Convergent Evolution

• Divergent evolution

• Complete Evolution

• Coevolution

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

• random chance

• natural selection

• non-random mating (sexual selection)

• artificial selection

 Genetic Drift is more likely to happen in... 

• aquatic populations
• small populations
• terrestrial populations
• older populations

All of the genetic information found in a population.

• population

• genetic drift

• evolution

• gene pool

A change in a gene, group of genes or chromosome that results in a change in the proteins.

• Replication

• Mutation.

• Translation

• Transcription
