Mechanisms of Evolution and Natural Selection

Front

Adaptations can be:

camouflage

,

ability to survive cold weather

,

hunting skills

,

all of the above

Back

all of the above

Front

A yellow morph and green morph of an insect lives in the rainforest canopy. You would expect:

Back

the green population to increase and the yellow to decrease

Front

Why are advantageous traits more likely to be passed onto offspring?

Back

Because they are more likely to survive and reproduce.

Front

Mutations are a change in what?

Back

DNA

Front

Why is the mouse population changing over time?

Back

The hawks eat more light mice than dark mice because they can see the light mice more easily

Front

Over the years, white mice became extinct and darker mice survived. This is

Back

directional selection

Front

Average phenotypes are favored in the environment, while extremes have lower survival rates. Options: seasonal selection, disruptive selection, directional selection, stabilizing selection

Back

stabilizing selection

Front

All the possible gene combinations in a population.

Back

gene pool

Front

Changes in the gene pool over time.

Back

Genetic Drift

Front

Organisms of the same species can no longer interbreed therefore creating two species.

Back

Speciation
