Front

Why do populations change over time?

Back

different traits are passed on depending on which traits are favored by the environment

Front

How do genes determine an individual’s traits?

Back

Genes are instructions for making protein molecules and protein molecules determine traits.

adaptive trait

Front

Which is NOT an example of mutations allowing the population to survive the environmental change?

• a mutation for fur to protect against a change in the temperature
• a mutation in poison to protect against an increase of snakes in the environment
• an organism continuing to express the same genes regardless of changes in the environment

Back

an organism continuing to express the same genes regardless of changes in the environment
