1.3 Artificial Selection

Front

What is artificial selection?

Back

Artificial selection is the process by which humans select desirable traits in organisms to be passed down to future generations.

Front

Give an example of artificial selection.

Back

An example of artificial selection is the breeding of dogs for specific traits such as size, color, or behavior.

What is the main difference between natural selection and artificial selection?

Back

In natural selection, traits that benefit the species are favored, while in artificial selection, traits that benefit humans are selected.

How does artificial selection impact biodiversity?

Back

Artificial selection can reduce biodiversity by favoring specific traits and leading to a decrease in the variety of traits within a species.

Front

What role do humans play in artificial selection?

Back

Humans actively choose which organisms to breed based on desired traits, influencing the genetic makeup of future generations.

Front

Can artificial selection lead to unintended consequences?

Back

Yes, artificial selection can lead to unintended consequences such as health problems in certain breeds due to a limited gene pool.

Front

What is a common method used in artificial selection?

Back

A common method used in artificial selection is selective breeding, where only individuals with desired traits are allowed to reproduce.

Front

How does artificial selection relate to agriculture?

Back

In agriculture, artificial selection is used to breed plants and animals for desirable traits such as higher yield, disease resistance, or better taste.

Front

What is the significance of genetic variation in artificial selection?

Back

Genetic variation is crucial in artificial selection as it provides the raw material for selecting desirable traits.
