COUC 504 : POPULATION SELECTION
CERTIFICATION SCRIPT 2026 QUESTIONS
WITH SOLUTIONS GRADED A+
◍ Probability Sampling Method.
Answer: A sampling method that relies on a random, or chance selection
methods so that the probability of selection population elements is known
◍ Sampling units.
Answer: units listed at each stage of a multi stage sampling design
◍ (1) Mutations cannot occur. (2) Gene flow cannot allow alleles into or out of
the population. (3) Individuals must pair ________. (4) Genetic drift does
not occur. (5) All genotypes have an _______ chance to survive.
Answer: randomlyequal
◍ Previous to the rise of industry in Britain, the frequency of the _______
phenotypes was predominant and enhanced the survival of moths..
Answer: light
◍ Secondly, the term q^2 represents the _______ ________ individuals within
a population..
Answer: homozygous recessive
◍ The remaining chance survivors now represent a new population with
altered ________ ______ frequencies compared to the original population..
Answer: gene pool
◍ Standard Error.
Answer: an estimate of the amount that a sample mean (avg.) is likely to
differ from the population mean
◍ Purposive Sampling.
, Answer: A non-probability sampling methods in which elements are
selected for a purpose, usually because of their unique position
◍ Interferential Statistics.
Answer: A mathematical told for estimating how likely it is that a statistical
result based on data from a random sample is representative of the
population from which the sample is assumed to have been selected
◍ Some organisms have very few differences in the amino acid sequences of
their proteins, yet are vastly different in _____ and function..
Answer: structure
◍ Sample.
Answer: A subset of population that is used to study the population as a
whole. The segment of population that is selected for investigationEx: the
use of public transit by Springfield residents
◍ Nonprobability Sampling Method.
Answer: Sampling Method in which the probability of selection of
population elements is unknown
◍ Snowball Sampling.
Answer: A method of sampling in which sample elements are selected as
they are identified by successive information or interviewers
◍ The lac repressor binds to what site within the lac operon?.
Answer: lacO
◍ Probability of Selection.
Answer: The likelihood that an element will be selected from the population
for inclusion in the sample. In a census of all elements of a population that
any elements in the population are sampled based on chance (say by tossing
a coin) the probability of selection for each element is one half. As the size
of the sample as a proportion of the population decreases, so does the
probability of selection
◍ The forearms of a bat, bird, whale, and cate all contain the same ________
