Evo Quiz Review

A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called

• Natural Selection

• Selective Breeding

• Random mutations

• Variations in a species

Why might it be helpful for a species to have a lot of variations?

• They can't be seen by predators

• If the environment changes, they might be better able to adapt

• It is helpful in asexual reproduction

• They don't recognize each other

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 trait is an acquired phenotype.

Which statement best describes the process of evolution?

• Populations can survive in different locations as long as conditions are favorable.

• Populations grow when resources are plentiful and competition does not occur.

• A lack of resources, such as water, can limit the number of species on Earth.

• The characteristics of a species can change over time in order for them to be better suited to survive.

How are genetics and evolution related?

• Parents with recessive genes die out due to natural selection.

• Only genes can be changed through natural selection.

• Only traits that are controlled by genes can be acted on by natural selection

• The genes of most surviving parents have only dominant alleles

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily
