7.4: Population Genetics Flashcards
(21 cards)
What are mutations?
a
Identify two examples of mutations that potentially could affect phenotype.
a
How do mutations affect genetic makeup of a population?
a
What is genetic drift?
a
What is the bottleneck effect?
a
How does the bottleneck effect modify genetic makeup of a population?
a
Identify one example of a population that has undergone the bottleneck effect.
a
What is the founder effect?
a
How does the founders effect modify genetic makeup of a population?
a
Identify one example of a population that has undergone the founder’s effect?
a
What is gene flow?
a
How does gene flow modify genetic makeup of a population?
a
Identify one example of a population that has undergone gene flow.
a
What is genetic variation?
a
Why is genetic variation important for a population’s survivability?
a
How does a decrease in genetic variation affect a population?
a
When there is a decrease in genetic variation, how does the population compare to other populations of the same
species?
a
What is the effect of mutations on genetic variation?
a
How does genetic variation lead to a variation in phenotypes?
a
Identify two examples of natural selection acting on phenotypes.
a
What are the three types of selection? Identify an example of each type of selection.
