A
ancestor.
B
descendant.
C
habitat.
D
mating practice.
4) All of the following are mechanisms for evolution except:
A
excellence
B
genetic variation
C
mutation
D
natural selection
5) Which of the following is NOT correct concerning natural selection?
A
It can happen due to predation on a population.
B
It results in an advantageous trait being more common in a population.
C
It occurs when individuals in a population express genetic variation that leads to their having more offspring.
D
Its purpose is to make perfect organisms.
6) A population of trees is suddenly dying due to global warming. Which of the following is most likely to happen?
A
Individual trees will quickly mutate so they adapt to the hot climate.
B
The trees will produce offspring better suited for hot environments allowing the species to survive.
C
Many trees will die and the population could go extinct unless some trees are growing in a cooler environment.
D
Individual trees will change their method of reproduction.
7) Which of the following is NOT evidence for evolution?
A
Fossils
B
Embryonic development
C
Personality tests
D
DNA testing
8) This basic mechanism for evolution is caused by random changes in the allele frequency of a population.
A
Genetic drift
B
Gene flow
C
Natural selection
D
Mutation
9) The combined genetic information of all the members of a particular population forms a _
A
phenotype
B
gene pool
C
genotype
D
niche
10) What is fitness?
A
Being the smartest animal in a population
B
Being successful in passing on genes to the next generation.
C
Being the strongest animal in a population

A
Neuron
B
Nerve cell
C
Somatic cell
D
Gamete
12) The type of selection in which organisms of average size have greater fitness than very large or very small organisms is called
A
artificial selection.
B
natural selection.
C
stabilizing selection
D
disruptive selection
13) How is sexual reproduction a source of genetic variation?
A
It leads to mutations that are inherently beneficial.
B
The offspring have more intelligence than the parents.
C
The crossing over that occurs during meiosis increases genetic variation.
D
The offspring have more mutations than the parents.

A
natural selection
B
vestigial structures
C
analogous structures
D
homologous structures

gene flow
D
selective mutations

natural selection
B
sexual selection
C
genetic drift
D
gene flow

A
The principle applies to individuals not populations.
B
The principle can be used to predict the frequency of alleles.
C
The principle states allele frequencies should remain constant unless factors cause them to change.
D
The principle applies to populations not individuals.
