Survival of the Fittest Quiz

Which of the following best explains how genetic variations can affect an individual's survival in a specific environment?

• Genetic variations always decrease an individual's chance of survival.

• Genetic variations can increase an individual's chance of survival by providing advantageous traits.

• Genetic variations have no impact on an individual's survival.

• Genetic variations only affect an individual's appearance, not survival.

• Green-shelled beetles will become more common.

• Brown-shelled beetles will become more common.

• Both green and brown-shelled beetles will remain equally common.

• Shell color does not affect beetle survival.

How does genetic variation contribute to the process of natural selection?

• It decreases the diversity of traits in a population.

• It provides different traits that may be advantageous in changing environments.

• It ensures all individuals in a population are identical.

• It prevents any changes in a population over time.

A population of rabbits has a mix of short and long fur. If the climate becomes colder, what is the expected outcome due to natural selection?

• Short-furred rabbits will become more common.

• Long-furred rabbits will become more common.

• Fur length will not change in the population.

• All rabbits will develop medium-length fur.

What role does the environment play in natural selection?

• It determines which traits are advantageous.

• It has no impact on natural selection.

• It ensures all traits are equally beneficial.

How can genetic variations lead to the evolution of a species?

• By reducing the number of traits in a population.

• By providing a pool of traits that can be selected for or against by the environment.

• By ensuring all individuals are identical.

• By preventing any changes in the population.

Which mathematical representation can be used to show the change in frequency of a trait over time due to natural selection?

• A pie chart showing trait distribution at one point in time.

• A line graph showing trait frequency over several generations.

• A bar graph showing trait frequency in a single generation.

• A scatter plot with no time component.
