Back

Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species.

Front

Why is genetic diversity important for survival?

Back

Genetic diversity increases the chances that some individuals in a population will survive environmental changes.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism's genome, which can lead to changes in traits.

Front

How do traits get passed from parents to offspring?

Back

Traits are passed from parents to offspring through genes, which are inherited from both the mother and father.

Front

What is the significance of variations among organisms?

Back

Variations among organisms are important for natural selection, as they provide the raw material for evolution.

Front

What is the role of competition in natural selection?

Back

Competition among organisms for resources leads to the survival of the fittest, where only the best-adapted individuals reproduce.

Front

What is an adaptation?

Back

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