MULTIPLE CHOICE QUESTION

30 sec • 1 pt

What is the primary mechanism by which evolution occurs according to Darwin's theory?

Genetic Drift

Natural Selection

Gene Flow

Mutation

Answer explanation

According to Darwin's theory, evolution primarily occurs through natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation.

MULTIPLE CHOICE QUESTION

Which of the following is a condition for a population to be in Hardy-Weinberg equilibrium?

Non-random mating

Large population size

High mutation rate

High gene flow

Answer explanation

A condition for Hardy-Weinberg equilibrium is a large population size, which minimizes genetic drift. Non-random mating, high mutation rates, and high gene flow disrupt this equilibrium.

How does gene flow affect the genetic variation between two populations?

Increases variation within populations and decreases variation between them

Decreases variation within populations and increases variation between them

Has no effect on genetic variation

Increases variation both within and between populations

Answer explanation

Gene flow introduces new alleles into a population, increasing genetic variation within that population. As alleles are shared between populations, it reduces the genetic differences between them, thus decreasing variation between populations.

Explain how a bottleneck effect can impact a population's genetic diversity.

It increases genetic diversity by introducing new alleles.

It reduces genetic diversity by drastically reducing population size.

It maintains genetic diversity by stabilizing allele frequencies.

It has no impact on genetic diversity.

Answer explanation

The bottleneck effect occurs when a population's size is drastically reduced, leading to a loss of genetic diversity. This reduction limits the gene pool, resulting in fewer alleles and decreased variability within the population.

MULTIPLE CHOICE QUESTION

Which type of natural selection favors individuals with extreme phenotypes over those with intermediate phenotypes?

Stabilizing Selection

Disruptive Selection

Directional Selection

Balancing Selection

Answer explanation

Disruptive Selection favors extreme phenotypes, leading to a population with two or more distinct forms. In contrast, Stabilizing Selection favors intermediate phenotypes, while Directional Selection favors one extreme.

MULTIPLE CHOICE QUESTION

Describe how the founder's effect can lead to genetic differences in a new population.

It results in a new population with genetic diversity similar to the original population.

It leads to a new population with reduced genetic diversity and different allele frequencies.

It causes the new population to have increased genetic diversity.

It has no effect on the genetic makeup of the new population.

Answer explanation

The founder's effect occurs when a small group establishes a new population, leading to reduced genetic diversity and altered allele frequencies compared to the original population, as only a subset of alleles is represented.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

What is an example of a structural adaptation in animals?

Migration patterns

Camouflage

Hibernation

Photosynthesis

Answer explanation

Camouflage is a structural adaptation that helps animals blend into their environment, enhancing their ability to avoid predators or ambush prey. Unlike migration, hibernation, or photosynthesis, it involves physical traits.
