- What are the two types of biological adaptation
- Behavioral and Genetic adaptation
- The prime advantage of sexual reproduction is:
- the ability to generate individual variation.
- Biological extiction is best defined as:
- the deletion of a specific sequence of DNA (genetic blueprint).
- When seeking out mates:
- males are usually the aggressors in seeking/attracting females for reproduction.
- Genetic diversity arises from:
- sexual reproduction.
- What role in biology does sexual reproduction play?
- Sexual reproduction generates diversity within a population.
- Mutations can be:
-
neutral.
detrimental.
