Unit 3 Bio Test

Front 1

Variation

Back 1

Different combinations of genetic info that organisms possess within a species

Front 2

Mutation

Back 2

Permanent change in the DNA of an organism

Front 3

3 Types of Mutations and examples

Back 3

1) Neutral: mutations that don't harm our help the organism
- e.g. Eye color
2) Harmful: mutations that reduce the organism's chances of survival and reproduction
- Cystic fibrosis in humans
3) Beneficial mutations: mutations that increase the organisms chances of survival and reproduction
-sickle cells help humans be resistant to malaria

Front 4

Artificial Selection

Back 4

Process of selecting and breeding organisms based on specific traits
-Takes many years
-reduces variability ( bad if disease comes along)
EXAMPLE: cats bred for appearance

Front 5

Selective advantages

Back 5

Genetic advantages that improve an organisms chances of survival and reproduction

Hint 5

Same as beneficial mutations
