Question of the Day
• How do mutations in a gene pool increase genetic diversity?
Get Ready for Review Notes- Pg. 20Title: 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.

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 A Population B
Population 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.
TAKE HOME MESSAGE:Genetic variation increases a species’ chance of survival
Variation good survival
