1What is a gene?

4What happens if you get a blood transfusion of the wrong type of blood?

- ATrue
- BFalse
8Why are "O" allele blood type proteins non functional?

- CToo big
- DA nucleotide has been added at the 258th position on the gene
- EWrong sequence of amino acids
9Who is the universal receiver of blood?
- AType B
- BType A
- CType AB
- DType O
10People who are type O can be transfused into anyone because they don’t have the protein that triggers an immune response that kicks out foreign blood cells.
- ATrue
- BFalse
11Type O people can get blood from anyone else
- ATrue
- BFalse
12What determines your blood type?
- ARandom (you are assigned a blood type by chance)
- BHeredity (you inherit it from your parents)
- CHemoglobin (your blood type develops based on how much hemoglobin is in your system)
13What effect does population size have on the “fate” of alleles?
- AThe bigger the population size the less diversity a population will have because the alleles will die out in the population.
- BThe bigger the population size the more diversity a population will have because the alleles will be able to remain in the population.
- CThe smaller the population size the more diversity a population will have because the alleles will be able to remain in the population.
14What effect does fitness have on the “fate” of alleles, in populations of different sizes?
- AAs the population increases the fitness has less of an effect on which allele disappears and influences which alleles are most prominent.
- BAs the population decreases the fitness has less of an effect on which allele disappears and influences which alleles are most prominent.
- CAs the population increases the fitness has more of an effect on which allele disappears and influences which alleles are most prominent.
- AAs the population increases the fitness has less of an effect on which allele disappears and influences which alleles are most prominent.
15What effect does population size have on whether a new, advantageous allele will survive or spread in the population?
- AAs the population size increases the allele with an advantage has a lesser change of surviving and spreading throughout the population before it dies out.
- BAs the population size decreases the allele with an advantage has a greater change of surviving and spreading throughout the population before it dies out.
- CAs the population size increases the allele with an advantage has a greater change of surviving and spreading throughout the population before it dies out.
16What effect does the “heterozygote advantage” have on the fate of alleles?
- AAs population increases, if an allele has a heterozygote advantage, there will be more of a chance that neither of the alleles will disappear.
- BAs population decreases, if an allele has a heterozygote advantage, there will be more of a chance that neither of the alleles will disappear.
- CAs population increases, if an allele has a heterozygote advantage, there will be less of a chance that neither of the alleles will disappear.
17Under what circumstances does genetic drift have the greatest effect?
- AWhen a population is fairly new
- BWhen a population is fairly old
- CWhen a population is fairly small
- DWhen a population is fairly large
18Under what circumstances does evolution have the greatest effect?
- AIf genetic drift is occuring
- BIf mass extinction is occuring
- CIf natural selection is occuring
- DIf mutation is occuring
- EIf migration is occuring
19What is the definition of population in terms of evolution?
- AAll individuals, all in the same species that live in a given area at the same period of time.
- BAll individuals, all in the different species that live in a given area at the same period of time.
- CAll individuals, all in the same species that live in a given area at different periods of time.
20What is evolution?
- AChange over time in the relative frequencies of allele variations in a population, genetic change in a population over time due to differing fitness (reproductive success).
- BChange over time in the relative frequencies of allele variations in a population, genetic change in a population over time due to similar fitness (reproductive success).
- CChange over time in the relative frequencies of allele variations in a population, genetic change in a population over time due to differing fitness (growth in bone size success)
21Which best describes genetic variation?
- AThe more genes have the more different alleles, the more varied the population.
- BThe less genes have the more different alleles, the more varied the population.
- CThe more genes have the more different alleles, the less varied the population.
22What is fitness in terms of evolution?
- AA measure of reproductive success compared to other in the same population and generation.
- BA measure of growth of bone size success compared to other in the same population and generation.
- CA measure of intelligence compared to other in the same population and generation.
23What are the four mechanisms of evolutionary change?
- AGenetic drift
- BMutation
- CMigration
- DGrowth
- ENatural selection
24Which best describes natural selection?
- AAny condition that a population is subject to (i.e. disease, sources of food, predators) that favors some alleles/traits.
- BAny condition that a population is subject to that causes random death or survival (earthquake, tsunami, volcanic eruption, landslide) not based on genetic traits
- CThe source of new alleles is spelling changes in DNA
25Which best describes genetic drift?
- AAny condition that a population is subject to (i.e. disease, sources of food, predators) that favors some alleles/traits
- BArrival of individuals into a new area
- CAny condition that a population is subject to that causes random death or survival (earthquake, tsunami, volcanic eruption, landslide) not based on genetic traits

- BEvery 100,000 years
- CAlways
- DNever
29Which best describes bottlenecks?
- AA loss of large percentage of population which results in all descendants come from a small amount of root ancestors
- BA small group that leaves a big group and thus they don’t have much genetic diversity because there are so few in the population
- CAny condition that a population is subject to that causes random death or survival (earthquake, tsunami, volcanic eruption, landslide) not based on genetic traits
30Which best describes the founder effect?
- AArrival of individuals into a new area
