1.
The difference between the original population and the surviving population is:
a)
The surviving population has more variety in the gene pool.
b)
The original population has more variety in the gene pool.
c)
The original population has a higher percentage of pink.
d)
There is no difference between the original and surviving population
2.
The founders effect can cause genetic drift to occur. Which of the examples below describes the founders effect?
a)
98% of the population dies of disease. The only ones that survive have red hair.
b)
A bird flies into her nest and lays her eggs.
c)
Two foxes from different areas of the state mate and have a litter of children.
d)
A small school of fish get lost in the ocean. Unable to find their way back to the rest of their species, they start a new life in this new area of the ocean
3.
The idea that organisms with the best traits for their particular environment will survive and reproduce better.
a)
Mutations
b)
Genetic Drift
c)
Natural Selection
d)
Gene Flow
4.
Mutations are a change in:
a)
DNA
b)
nucleus
c)
TRNA
d)
mRNA
5.
The studies of changes between black and light color in populations of the peppered moth show that
a)
Natural selection can quickly change the color percentages in a population
b)
An individual moth can change color to make sure it survives
c)
Predators only like to eat dark colored moths
d)
Natural selection changes a population in a way that can never be reversed
6.
The northern elephant seal population was reduced by over-hunting to 20 seals in the 1890s. Although the population had rebounded to over 30,000 individuals by 1974, 24 genes were identical in all individuals in the new population. This is an example of:
a)
Gene flow
b)
Mutations
c)
Bottleneck
d)
Founder effect
7.
What is the difference between genetic drift and natural selection?
a)
Genetic drift never occurs in nature, but natural selection does
b)
Genetic drift happens on purpose, natural selection is random.
c)
Genetic drift happens randomly, while natural selection is caused by competition for resources and one's ability to hide from predators
d)
Genetic drift is identical to natural selection
8.
What causes mutations?
a)
Diabetes
b)
Oxygen in the bloodstream
c)
They are a trait that you get from each of your parents
d)
Mistakes in DNA replication or protein making
9.
Are all mutations bad?
a)
Yes
b)
No
10.
What word describes a trait that helps an organism survive in its environment?
a)
Natural Selection
b)
Camouflage
c)
Mutation
d)
Adaptation
11.
Do organisms "decide" to evolve and change?
a)
Yes, they know they need to change to survive
b)
No, the population changes over time because of natural selection
12.
Why are advantageous traits more likely to be passed onto offspring?
a)
Because they come from recessive alleles.
b)
Because the trait is an acquired phenotype.
c)
Because they are more likely to survive and reproduce.
d)
Because they come from dominant alleles.
