How is Genetic Variation related to an organism's ability to adapt to its environment

• when genetic variation low the ability to adapt is high

• when genetic variation is high the ability to adapt is low

• When genetic variation is low the ability to adapt is low

• when genetic variation is high the ability to adapt is high
