Quiz about Population Genetics

Question 1

A gene pool is

all of the alleles in a population

all of the alleles in an individual

Answer

a body of water filled with fish

Answer

all of the bases in one strand of DNA

Question 2

Ten years ago, in a small population of ducks, two sizes of eyes were observed, large and small. Three ducks have large eyes and 7 have small. 2 of the large-eyed ducks are randomly hit by cars and killed. Today, no large-eyed ducks are present in the population. Which term best describes this scenario?

Accepted Answer

bottleneck

Answer

gene flow

Answer

mutation

Answer

founders

Question 3

Mutations are important because they bring about

Accepted Answer

genetic variation needed for a population to evolve

Answer

death of the organism in which they develop

Answer

benefits for the individual, not for the population

Answer

changes in genotype, but not phenotype

Question 4

Someone steps on some bugs and randomly removes their alleles from the population. This is an example of

Question 6

A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population. Which term describes this scenario?

Accepted Answer

Founder Effect

Answer

Natural Selection

Answer

Non-random mating

Question 7

The Hardy-Weinberg Model is...

Accepted Answer

a mathematical tool that biologists can use to predict allele frequencies and determine whether or not evolution is occurring within a population.

Answer

available at local hobby stores and retailers throughout the Greater Tazewell area.

Answer

always occurring within individual organisms in nature.

Answer

only useful in the lab and cannot be practically applied to real-world populations of organisms.

Question 10

Select the best answer based on the image.

Accepted Answer

Answer

Genetic Drift

Question 11

Which is not true about cheetah populations?

Accepted Answer

They have high levels of genetic variation.

Answer

They have experienced bottlenecks in their evolutionary history.

Answer

They are prone to extinction.

Answer

They are not likely to survive environmental changes due to their similarities.

Question 12

Which of the following statements best describes what will most likely occur to the moth populations in the image above?

Accepted Answer

The light moths will be captured by predators more easily than the dark moths, and the population of dark moths will rise.

Answer

The light moths will be captured by predators more easily than the dark moths, and the population of light moths will rise.

Answer

The dark moths will be captured by predators more easily than the light moths, and the dark moths will probably go extinct.

Answer

The light moths will change their wing color to match that of the dark moths.

Question 13

Suppose wing span is a polygenetic trait. Those with both very large and very small wing spans do not survive. This is:

Accepted Answer

Stabilizing selection

Answer

Disruptive selection

Answer

Directional selection

Answer

Divergent selection

Question 14

The random change to allele freqencies of a population is known as genetic drift.

Accepted Answer

True

Answer

False

Question 15

Which of the following is NOT part of the founder effect

Accepted Answer

Can be caused by a natural disaster

Answer

Some members of the group migrate

Answer

The new population can have a different allele frequency

Answer

Both the original population and new population survive

Question 16

If there are 50 flowers, 30 red (RR), 15 pink (Rr) and 5 white (r), what the frequency of the recessive allele?

Accepted Answer

25%

Answer

5%

Answer

10%

Answer

20%

Question 17

Which of the following IS NOT part of the Bottleneck Effect?

Accepted Answer

The populations are geographically separated

Answer

The new population can have a new allele frequency

Answer

The new population size decreases

Answer

Can be caused by a natural disaster

Question 18

Which of the following would PREVENT evolution from occurring?

Accepted Answer

Non-random mating

Answer

Large population

Answer

Mutatons

Answer

Immigration of new individuals

Question 19

Sympatric speciation occurs when 2 populations in the same region no longer interbreed.

Accepted Answer

True

Answer

False

Question 20

A large highway separates a population of mountain lions resulting in what type of speciation?

Accepted Answer

allopatric

Answer

sympatric

Answer

founder

Answer

directional

Question 21

Which of the following best describes genetic drift?

Accepted Answer

A random change in allele frequencies within a population

Answer

The movement of alleles between populations

Answer

The selection of advantageous traits

Answer

The mutation of genes over time

Question 22

In a population of rabbits, a sudden flood drastically reduces their numbers. The surviving population has different allele frequencies than the original. What is this an example of?

Accepted Answer

Bottleneck Effect

Answer

Founder Effect

Answer

Gene Flow

Answer

Natural Selection

Question 23

What is the primary focus of population genetics?

Accepted Answer

Answer

Studying the genetic makeup of individuals

Answer

Analyzing the physical traits of organisms

Answer
