Darwin found that many species on the Galapagos Islands resembled species on the nearest mainland.
False
True
3
Which of the following is an example of allopatric speciation?
Two insects begin to mature in different seasons
A hybrid offspring is sterile
A forest fire destroys a habitat
An earthquake separates a population into two regions
4
Which is an example of artificial selection?
Volcanic lava allowing black fur to be preferred
Drought resulting in larger beaks being beneficial.
Farmers selecting the largest fruit seeds to propagate.
Cold weather selecting against long ears in rabbits
5
In a population of frogs, 9% have spots (recessive) and 91% don't. What are p and q?
p = 0.49, q = 0.51
p = 0.09, q = 0.91
p = 0.60, q = 0.40

6
When a diploid plant fertilizes a tetraploid plant, resulting plants will be_____.
triploid and sterile
triploid and fertile
diploid and sterile
tetraploid and fertile.
7
The fossil record shows that the earliest life forms were eukaryotes.
True
False
8
Why do individuals not evolve, but rather populations do?
Adaptations are acquired as organisms encounter stressors
Adaptations are acquired as organisms learn new behaviors
Mutations for adaptations occur due to exposure to toxins
Mutations for adaptations occur as genes are passed on
9
Mate-attracting features such as bright plumage on a male duck result from
directional selection.
disruptive selection.
intersexual selection.
intrasexual selection.
10
All provide evidence for evolution EXCEPT:
embryology
vestigial structures
mutations
homologous structures
11
Speciation without geographic isolation
Diversifying
Allopatric
Fusion
Sympatric
12
The various beaks of Darwin's finches are an example of
Natural Selection (Adaptive Radiation)
Sexual Selection
Genetic Drift
Gene Flow
13
Which is an example of gene flow?
New organisms migrate into the population
Larger males are selected for mating
Mutations occur at random in population
A natural disaster wipes out half of the population
14
Antibiotic resistant bacteria is an example of
Disruptive selection due to size specifications
Artificial selection due to human interference
Natural selection due to a mutation
Sexual selection due to reproductive success
15
Different breeding seasons between two species is an example of temporal isolation.
True
False
16
Each island in the Galapagos chain has only one unique finch species.
True
False
17
Fusion can occur in a hybrid zone.
True
False
18
Natural selection starts with the creation of new alleles that are directed toward improving an organism's fitness.
False
True
19
Speciation is
necessary for adaptation.
a form of microevoltion.
an event that has occurred only a few times in the history of Earth.
responsible for the diversity of live.
20
The biological species concept defines a species as
Population that is able to mate successfully
Populations that live in the same ecosystem
Population that can mate and produce fertile offspring
Groups of organisms in a population that share traits
21
Which are homologous structures?
insect antennae, bird eye
bat wing, whale flipper
bat wing, fish scales
butterfly wing, bat wing
22
Gene flow reduces genetic differences between/among populations.
True
False
23
Speciation resulting from a geographic barrier
Fusion
Hybridization
Allopatric
Sympatric
24
Why can Hardy-Weinberg equilibrium only occur in large populations?
Genetic drift is stronger in small populations
Random mating is virtually impossible in large populations
Likely to have more variable environments
Less chance for natural selection to occur
25
Many of the vegetable varieties you eat were produced through natural selection.
True
False
26
What is the selective advantage that keeps the sickle cell trait in populations?
The homozygous dominant are at risk of malaria
Those afflicted with sickle cell often suffer
The sickle cell trait prevents leukemia
The heterozygous trait protects against malaria
27
Gametes not compatible
Temporal isolation

True
False
29
Which is not a pre-zygotic reproductive barrier?
Habitat isolation
Temporal isolation
Behavioral isolation
Hybrid sterility
30
An adaptation
cannot be altered
evolves b/c it improves the mating success
affects the fitness of an organism if it is altered
can be shaped by genetic drift
31

amphibians
crocodiles
32
Ultimate source of new alleles in a population
