COUC 504 : POPULATION SELECTION
FINAL TEST 2026 QUESTIONS WITH
CORRECT ANSWERS GRADED A+
◍ If allowed to proceed unopposed by any other mechanism of evolution,
migration will....
Answer: eventually homogenize allele frequencies across populations
◍ Standard error.
Answer: theoretical and statistically determined average deviation from the
sample mean that you would most likely get if you sampled everyone in the
population
◍ Reliability.
Answer: the degree to which a value is replicable and consistent across
raters and test sessions
◍ When does frequency dependent selection occur?.
Answer: When the fitness of allele or genotype depends on its frequency in
polulation
◍ Inter-item reliability.
Answer: the degree to which scores on one or more items in a test are
similar to other items on the test
◍ Bias.
Answer: A systematic error in an estimate which could lead to a result that
does not represent the true representation of that population
◍ Random selection.
Answer: a selection process or procedure that assures that the different units
in your population are selected by chance
, ◍ Polymorphic loci have at least....
Answer: two alleles
◍ What two ways can Mean Heterozygosity be interpreted in?.
Answer: Fraction of individuals in a population that are heterozygous at a
given loci.Fraction of loci that are heterozygous in an individual.
◍ What is the mutation selection balance?.
Answer: Rate at which mutation creates copies of the deleterious allele is
equal to the rate at which selection eliminates copies of the deleterious allele
from the population.
◍ What is Evolution?.
Answer: A change in allele frequencies in populations across generations
◍ What are quantitative traits?.
Answer: Traits that show continuous variation that we can measure (ie
height in humans)
◍ Split-half reliability.
Answer: If you take ½ the test and compare scores to the other ½ of the test,
do they lead to the same value?
◍ Variance.
Answer: average variation of scores in a sample or population
◍ Standard deviation.
Answer: average value of distance/difference from the sample mean from all
participants sampled
◍ Systematic random.
Answer: sampling method where you determine randomly where you want
to start selecting in the sampling frame and then follow a rule to choose
every xth individual from the list
◍ Gene duplications can result if:.
Answer: Homologous chromosomes fail to separate during meiosis ISister
chromatids did not separate during meiosis II
