Back

A trait is any inherited characteristic, while an adaptation is a specific trait that enhances survival.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a species.

Front

How does genetic variation contribute to evolution?

Back

Genetic variation provides the raw material for evolution, allowing populations to adapt to changing environments.

Front

What is the role of DNA in inheritance?

Back

DNA carries the genetic information that is passed from parents to offspring.
