Answers
1
Which of these increases the chance a deleterious recessive allele will stay in the gene pool?
death of homozygous recessive individuals
polyploidy
interspecific mating
heterozygote advantage
2
Type of selection shown
disruptive
directional
stabilizing
3
Whales, penguins, and sharks having similar body shapes/fins/flippers =
coevolution
sympatic speciation
adaptive radiation
convergent evolution
4
Tiktaalik is a _______ fossil because it shows characteristics of both fish and amphibians.
pseudo
transitional
heterozygotic
vestigial
5
Similar structures of the same embryonic origin are called
vestigial organs
analogous structures
homologous structures
pseudo structures
6
Sexual dimorphism results from
kin selection
sexual selection
coevolution
genetic drift
7
Analogous structures ______ evidence of shared recent ancestors
show
do not show
8
Pre-zygotic barrier in which reproductive parts of different species are unable to connect
behavioral isolation
mechanical isolation
gametic isolation
hybrid breakdown
9
Kin selection
Kills some individuals but saves relatives with shared genes
Leads to bottleneck effect because population gets smaller
leads to reproductive isolation
Shuffles genes with most mutations
10
Migration results in
random mating
differential reproductive success
gene flow
hybrid infertility
11
Which of these would most likely result in a population NOT in Hardy-Weinberg equilibrium ?
no gene flow
random mating
sexual selection
large population
12
ALL of the following are sources of genetic variation in populations EXCEPT
Recombination during fertilization
Crossing over in meiosis
mistakes in DNA replication
mistakes in translation of structural genes
13
In the Hardy-Weinberg equation there is a 2 in the 2pq term because
This term has both p and q so you have to add 2
There are two ways to get heterozygous alleles
Heterozygotes always have an advantage so it counts more
14
Darwin's finches are an example of
sexual selection
adaptive radiation
kin selection
convergent evolution
15
Which of the following explains how insects become pesticide resistant?
Insects born with resistance genes survive and reproduce
Insects in population slowly adapt to presence of pesticide
Insects learn to avoid areas with pesticides
Exposure to pesticide causes mutations making some resistant
16
The smallest unit that can evolve is a
gene
population
genotype
an individual organism
17
Organism with more than 2 sets of chromosomes
homologous
allopatric
sympatric
polyploid
18
All of these are parts of Darwin's theory EXCEPT
natural variation
inheritance of acquired traits
overpopulation
survival of the fittest
19
Which of the following supports the idea that all organisms share a common ancestor?
All living things reproduce
All living things evolve
All organisms require energy
All living things use nucleic acids for their genetic code
20
The sudden appearance of polyploid individuals due to mistakes in meiosis is an example of
allopatric speciation
stabilizing selection
sympatric speciation
directional selection
21
The ultimate source of genetic variation in a population is
reproductive isolation
mutation
natural selection
the environment
22
Differences in size or appearance between the male and female animals
sexual dimorphism
kin selected traits
sexual genotypes
genetic drift
23
The best example of gene flow is
Earthquake creates canyon splitting a population
Development of polyploidy plants
Genes shuffled by crossing over
Wind blows pollen from one population to another
24
The bottleneck effect results in
heterozygote advantage
the disappearance of recessive alleles
a few individuals colonizing an isolated area
certain alleles being over represented due to chance
25
In the Hardy-Weinberg equations, p
2
represents
Recessive allele
homozygous recessive individuals
Dominant allele
homozygous dominant individuals
26
Type of selection that leads to speciation
kin
disruptive
directional
stabilizing
27
Which of the following is a measure of an organism's fitness?
how strong it is when competing with others for food
How quickly it matures
number of fertile offspring it produces
ability to withstand environmental extremes
28
If q
2
= 0.36, what is the frequency of the dominant allele?
0.64
0.4
0.6
0.16
29
Type of selection shown here
stabilizing
disruptive
directional
30
Dull colored male birds don't get picked to reproduce; Very bright ones get eaten by predators
directional selection
stabilizing selection
disruptive selection
31
Species breeding at different times of year exemplify which type of pre-zygotic barrier?
behavioral isolation
gametic isolation
habitat isolation
temporal isolation
32
During the Industrial revolution, what happened to the peppered moths in England?
Light moths increased; dark moths decreased in population
Dark moths increased; white moths decreased in population
White moths changed their color to blend in with trees
All the moths died from pollution
33
Why do male peacocks have ridiculously big tails?
kin selection
heterozygote advantage
stabilizing selection
sexual selection
34
Different species may be prevented from interbreeding by responding to different mating dances
hybrid sterility
gametic isolation
mechanical isolation
behavioral isolation
35
If allele frequencies in a population change that means evolution _____ happened.
HAS NOT
HAS
36
Why do bacteria become resistant to antibiotics?
bacteria get used to antibiotics and they have less effect
humans become resistant to antibiotics not bacteria
antibiotics cause mutations in bacteria
resistant bacteria survive and reproduce
37
A bird wing and a butterfly wing are examples of _________ structures.
vestigial
analogous
homologous
transitional
38
Any inherited characteristic that increases an organism's chance of survival
adaptation
vestigial organs
fitness
