Question of the Day How do mutations in a gene pool increase genetic diversity?

Get Ready for Review Notes- Pg. 20 Title: Genetic Variation

Genetic means Genes DNA

Variation means: Differences variety

Genetic Variation Definition- Differences in traits ** the more genetic variation, the more likely a species is to survive.**

Independent Activity: Genetic Variation Worksheet (15 min)- Pg. 21

What causes genetic variation? A MUTATION: – A change in DNA sequence – Occur naturally or via chemicals or radiation

Quick write: Pg. 21 Why is genetic variation important to a species?

Answer: If there is genetic variation, then some individuals in a species will be more fit than others. This ensures that some individuals of the species will survive and keep the species going. If there is no genetic variation, then all individuals will be exactly the same. This could be deadly if there is a change in the environment. The species could go extinct because none will be fit for the environment.

Example: Pg. 21 Which population of hares has a better chance of survival as a species? Why Population APopulation B

Because it has more genetic variation than population A so there will be some individuals that are more fit if the environment were to change. Thus the species has a higher chance of survival.
