TPS on Evolution
• Explain why genetic variation is a prerequisite
for evolution. List three factors that can result
in more variation in the population.
• Why do only a very small fraction of mutations
become widespread in a population?
• A fruit fly population has a gene with two
possible allele variations. It is shown that the
frequency of the dominant allele is 70 %.
What is the frequency of the homozygous
dominant, heterozygous and homozygous
recessive individuals?
• In a population of 10,000 humans, 2 had
polydactily, a dominant disorder. What
percent of the population is heterozygous?
• List the five factors that are required to be
present for a Hardy-Weinberg equilibrium.
• Compare and contrast homology and analogy.
• Explain how the following statement is
inaccurate: “Anti-HIV drugs have created
resistance in the virus.”
• Most fossils are found in sedimentary rocks.
Where in these would you find the oldest and
youngest fossils?
• If you discovered a fossil of an extinct mammal
that lived high in the Andes, would you predict
that it would more closely resemble present-day
mammals from South American jungles or
present-day mammals that live high in African
mountains? Why?
• Describe what genetic drift is and how it
contributes to evolution.
• Describe through an example how heterozygous
organisms can have an evolutionary advantage
over the homozygous phenotypes.
• Summarize key differences between allopatric
and sympatric speciation.
• Two different fruit fly species live in the same
parts of the Hawaiian Islands. They both have
very elaborate courtship rituals that are quite
different from each other. What type of
isolation is this?
• List four evidence that can be used to set up
phylogenic relationships. Point out one
benefit and one disadvantage of using each.
• State the rule of parsimony. Why do you think
it is useful for setting up evolutionary
• Explain the origin and consequences of oxygen
in the atmosphere.
• Describe the endosymbiotic theory and state 3
• Explain the RNA world hypothesis and give two
• Explain the two hypotheses that describes how
simple organic molecules may have originated.
What is the evidence?
