ACL Evolution Quizizz (Part 2)

What is a gene pool?

• all of the different alleles in a population

• all of the different alleles in one area of the planet

• a collection of all beneficial alleles in individuals

• the percentage of an allele in a population

A population of poison dart frogs has 4 red frogs and 6 blue frogs. What is the allele frequency of the blue allele?

• 20%

• 40%

• 60%

• 80%

A wildfire comes into an area of 300 trees and destroys all but 10 of them. Eventually, the 10 trees will reproduce and create more trees. What is this situation an example of?

• behavioral isolation

• bottleneck effect

• founder effect

• temporal isolation

Due to severe climate change effects in the winter, a small group of geese decide to break off from the main population and live permanently in the Gulf Coast. The geese reproduction and create a new large population of birds. What is this situation an example of?

• founder effect

• natural selection

• bottleneck effect

• gene pool

Which of the following is a possible cause of a bottleneck effect?

• different mating times

• migration

• major flood

• new adaptation

True or False. Genetic drift can result in the evolution of a population.

• True

• False

A population of rhinos in a savanna in Africa migrates and joins a population of rhinos at a water hole. Over time, the now larger population of rhinos evolves. Which cause of evolution does this example represent?

• small population size

• genetic drift

• natural selection

• gene flow

What may bring about a new adaptation in a population?

• mutation

• genetic drift

• natural selection

• behavioral isolation

Within a population of chickens, chickens with black feather only breed with other chickens with black feathers. What is this an example of? Will this result in evolution?

• gene flow; no

• gene flow; yes

• non-random mating; no

• non-random mating; yes

The creation of 2 new species from 1 species occurs because of

• reproductive isolation.

• genetic drift.

• mutation.

• microevolution.
