Review: Adaptations & Natural Selection

Front

What is asexual reproduction?

Back

A type of reproduction that involves only one parent, leading to offspring that are genetically identical to the parent.

Front

What is sexual reproduction?

Back

A type of reproduction that involves two parents, resulting in offspring with genetic variation.

Front

What is genetic variation?

Back

Differences in DNA among individuals in a population, which can lead to different traits.

Front

Why is genetic variation important for natural selection?

Back

It provides a range of traits that selection can act upon, increasing the chances of survival.

Front

What is an adaptation?

Back

A trait that helps an organism survive and reproduce in its environment.

Front

Give an example of a physical adaptation in animals.

Back

The thick fur of polar bears helps them stay warm in cold climates.

Front

What is natural selection?

Back

The process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the role of competition in natural selection?

Back

Organisms compete for limited resources, and those with advantageous traits are more likely to survive.

Front

What is camouflage?

Back

A type of adaptation that allows an organism to blend in with its environment to avoid predators.

Front

What is the significance of a gene pool?

Back

The total collection of genes in a population, which affects genetic diversity.
