Unit 5: Evolution
What did T Rex taste like?
Vocabulary:
Gene pool: the combined genetic information of all the individuals of a population.
relative frequency: the number of times that a gene occurs in a gene pool compared with the number of times
other alleles occur.
single-gene trait: trait controlled by a single gene.
polygenic trait: trait controlled by two or more alleles.
directional selection: form of natural selection in which the entire curve moves, when individuals at one end of
the curve have a higher fitness that those at the middle or other end of the curve.
stabilizing selection: when individuals at the center of the curve have a higher fitness that those at either other
ends of the curve.
disruptive selection: when individuals at the upper and lower end of the curve have a higher fitness that those at
either ends of the curve.
genetic drift: random change in allele frequencies that occurs in small populations.
founder effect: change in allele frequencies as a result of migration of a small sub group population.
Hardy-Weinberg principle: allele frequencies will remain constant unless one or more factors cause the
frequencies to change.
genetic equilibrium: when allele frequencies remain constant.
Speciation: formation of a new species.
reproductive isolation:when member of two species cannot interbreed.
behavioral isolation : when members of two species can interbreed, but have different mating rituals or customs.
geographic isolation: when members of two species cannot interbreed due to geographical barriers.
temporal isolation : when members of two or more species reproduce at different times.
Standards: Concept 4: Biological Evolution
Understand the scientific principles and processes involved in biological evolution.
S4-C4-PO2. Explain how genotypic and phenotypic variation can result in adaptations that influence an
organism’s success in an environment.
S4-C4-PO3. Describe how the continuing operation of natural selection underlies a population’s ability to adapt
to changes in the environment and leads to biodiversity and the origin of new species.
