Questions: Question 3 (1 point) is the study of all of the alleles or genes in a population over time. macroevolution population genetics gene pools microevolution Question 4 (1 point) One principle of Natural selection is that variations in characteristics are inherited. Which of the following is an example of this principle? All bunnies in a population display the same coat color. Some beetles are dark, and some are light. There is not enough food for every giraffe to eat, so some die. Ladybugs with many spots tend to have offspring with many spots, while bugs with no spots tends to have offspring with no spots.

The answer to Question 3 is: population genetics.

Explanation:

• Macroevolution: This refers to large-scale evolutionary changes that occur over long periods of time, such as the formation of new species.
• Population genetics: This is the study of the distribution and changes of allele frequency in a population, as influenced by evolutionary processes such as natural selection, genetic drift, mutation, and gene flow.
• Gene pools: This term refers to the complete set of different alleles in an interbreeding population.
• Microevolution: This refers to small-scale changes in allele frequencies within a population over a short period of time.

The correct answer is population genetics because it specifically deals with the study of alleles or genes in a population over time.

The answer to Question 4 is: Ladybugs with many spots tend to have offspring with many spots, while bugs with no spots tend to have offspring with no spots.

Explanation:

• All bunnies in a population display the same coat color: This does not illustrate variation in characteristics.
• Some beetles are dark, and some are light: This shows variation but does not indicate inheritance.
• There is not enough food for every giraffe to eat, so some die: This describes a struggle for existence, not inheritance of characteristics.
• Ladybugs with many spots tend to have offspring with many spots, while bugs with no spots tend to have offspring with no spots: This clearly shows that variations in characteristics (number of spots) are inherited.

The correct answer is the last one: Ladybugs with many spots tend to have offspring with many spots, while bugs with no spots tend to have offspring with no spots.
