AP Bio Natural Selection

What is one difference between natural selection and artificial selection?

• Natural selection involves humans; artificial selection does not involve humans.

• Natural selection does not involve humans; artificial selection involves humans.

• Natural selection takes longer than artificial selection.

• Artificial selection only involves plants; Naturals selection only involves animals.

What is one problem with artificial selection?

• It takes thousands of years

• It removes diversity and bad traits can surface

• It promotes biodiversity of the species

• It can only happen once a year

Which is not true about natural selection?

• There must be diversity in the population

• It is driven by natural processes like predators or weather conditions

• Humans are involved and can select the most desirable organisms

• Predators, geological activity, and weather can all have an impact on organisms

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

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the organism knew it needed that trait, survives, and passes it on.

Eider ducks live in the ocean and have a layer of warm feathers underneath their regular feathers. They can have thin feathers, medium feathers, or thick feathers. These feathers help the ducks stay warm in cold water. Ducks with thicker feathers are more likely to stay warm and survive in cold water. But, in warm water, thicker feathers can make the ducks overheat and die. The population of ducks shown above lives in an environment that has always had very cold water. Could there ever have been ducks with thin feathers in this population?

• No ducks could have been born with the thin-feather trait because none of the adult ducks had that trait to pass down.

• No ducks could have been born with the thin-feather trait in the past, but some with that trait could be born in the future if the environment changes to be warmer.

• A duck could have been born with a mutation in its genes for the thin-feather trait and lived for a little while, but it would have been more likely to die before it had offspring.

• A duck could have been born with a mutation in its genes for the thin-feather trait, but having a mutation in its genes would have caused it to die when it was born.
