Chapter 15 Bio: Evolution on a Small Scale

Which individual would be considered the fittest?

Which of the following does not generate genetic variation within a population?

If p = 0.6, what is q?

If half of a population is homozygous recessive, what is p?

Which of the following is not one of the conditions required for Hardy-Weinberg equilibrium?

What might occur in moth populations if pollution from industry was cleaned up, and the color of tree bark returned to its natural color?

Why do prokaryotes and eukaryotes differ in their reliance on mutations for generating genetic variation?

What statement is false regarding the differences between a biological species and subspecies?

Which Hardy-Weinberg condition is violated by sexual selection?

Which of the following examples is one of genetic drift?

Which of the following does not result in a decrease of genetic variation?

If the average leg size of a reptile continually got smaller through generations, this would be an example of

If people with freckles preferentially mate with other people with freckles, this would be an example of

All of the genes and all of their associated alleles within a population represent the population's

The figure shown here represents stabilizing selection. What happens when an individual is produced that possesses a trait far away from the mean value?

In the Hardy-Weinberg formula, what does q2 represent?

If a population recovers to its original population size after experiencing a bottleneck, which statement is correct regarding this population?

What characteristic do a bottleneck and a founder effect have in common?

Why does the malaria disease persist in the human population?

Which of the following is most likely to lead to two distinct species?

In the figure shown here, the bell-shaped curve representing the population illustrates that *see pic*

In the figure shown here, flower color of a population is distributed in a bell-shaped normal curve. If the pink flower color increases in frequency in the population, this would illustrate

In the figure shown here, flower color of a population is distributed in a bell-shaped normal curve. If the white flower color increases in frequency in the population, this would illustrate

In the figure shown here, flower color of a population is distributed in a bell-shaped normal curve. If the white and yellow flower colors increase in frequency in the population, this would illustrate

T/F: Dominance causes an allele to become more common.

T/F: The conditions required by the Hardy-Weinberg equilibrium are commonly found in nature.

The frequency increase of dark phenotypes in response to increased pollution is called

What is the typical mutation rate within a cell?

Microevolution is not influenced by which of the following?

A female peacock chooses a male as a mate based on his showy plumage and courtship dance. This is an example of

In random mating

If p2 = 0.04, what is the frequency of homozygous recessives in the population?

A group of field mice cross a highway and join a new population of field mice on the other side, producing offspring with this population. This is an example of

Today, cheetahs show extreme genetic similarity. This is evidence of

The effects of genetic drift are more significant in

Biotic environments that influence natural selection includes all but which of the following?

Which of the following is most likely an example of a founder effect event?

In the process of natural selection, individuals that are most fit are the ones that are

The usage of the insecticide DDT to control mosquitos resulted in

Directional selection in the modern horse is demonstrated by

British land snails primarily occur in two extreme phenotypes. This is an example of

Individuals who inherit sickle cell disease, a recessive disorder, tend to die at an early age while individuals who are homozygous for their blood cells survive. How does the recessive allele persist in the population?

In what type of environment is being heterozygous in regards to the sickle cell trait an advantage?

T/F: Natural selection will favor directional, stabilizing and disruptive selection in the same population simultaneously.

A fraction of the original green frog population survives to reproduce and generate the new population. If the survivors of the original population survived by chance, then this event is an example of

If the survivors of an original population survived due to specific phenotypes that they possessed, then this event is an example of

T/F: Polydactylism (possessing more than five fingers per hand) within the Amish population in Pennsylvania is considered an example of founder effect. This is because the frequency of polydactylism among the Amish in Pennsylvania is identical to its frequency among the Amish population in Germany.

What is the genotype of an individual that is lives in protection from both sickle cell disease and malaria?

A population of bacteria is in Hardy-Weinberg equilibrium. However, through repeated exposure to an antibiotic, the frequency of the recessive allele is rapidly increasing. What is the most likely explanation for this response?

Microevolution is the term that applies to which of the following?
