Natural and Artificial Selection

Front

What is natural selection?

Back

Natural selection is the process by which organisms that are better adapted to their environment tend to survive and produce more offspring.

Front

What is artificial selection?

Back

Artificial selection, also known as selective breeding, is the process by which humans breed plants and animals for specific traits.

Front

What is an example of natural selection?

Back

The survival of the fittest, where faster animals escape predators more effectively.

Front

What is an adaptation?

Back

An adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What role do mutations play in evolution?

Back

Mutations introduce new genetic variations that can lead to adaptations.

Front

What is genetic recombination?

Back

Genetic recombination is the process during meiosis where genetic material is shuffled, creating new combinations of genes.

Front

How does selective breeding differ from natural selection?

Back

Selective breeding is controlled by humans, while natural selection occurs without human intervention.

Front

What is a selective pressure?

Back

A selective pressure is an environmental factor that affects an organism's ability to survive and reproduce.

Front

Why are advantageous traits more likely to be passed on?

Back

Advantageous traits increase an organism's chances of survival and reproduction.

Front

What is the significance of variation in a population?

Back

Variation is essential for natural selection, as it provides the raw material for evolution.
