10. How is the Hardy-Weinberg principle applied to PKU?
Concept 23.3: Natural selection, genetic drift, and gene flow can alter allele frequencies in a population

selection)
Diploidy
Heterozygote advantage
Frequency dependent selection
Neutral variation

The Origin of Species
Chapter 24 Guided Reading Notes and the MUST SEE
Bozeman video #8 Speciation
Concept 24.1: The biological species concept emphasizes reproduction isolation
1. Define:
a. Speciation
b. Macroevolution
c. Microevolution
2. Explain what reproduction isolation is in terms of Prezygotic barriers Postzygotic barriers in the following table.
Reproductive
Barriers
Prezygotic Barriers – impede mating or fertilization if mating does occur
Postzygotic Barriers – prevent hybrid
zygotes to be fertile adults

3.
Explain other definitions of a species
a. Morphological species
b. Ecological species
c. Phylogenetic species
Concept 24.2: Speciation can take place with or without geographic separation
4. What is allopatric speciation?
a. What is the process for this type of speciation?
b. What is the evidence that supports this type of speciation?
5. What is sympatric speciation?
a. Explain polyploidy in terms of speciation
b. Explain how sympatric speciation can occur as a result of
i. Habitat differentiation
ii. Sexual selection
Concept 24.3: Hybrid zones provide opportunities to study factors that cause reproductive isolation
6. What is a hybrid zone and how can these areas impact gene flow and speciation?
Concept 24.4: Speciation can occur rapidly or slowly and can result from changes in few or many genes
7. What is punctuated equilibria?
8. How can speciation differ between types of organisms?
9. What can affect the rate of speciation?
10. How can speciation lead to macroevolution?
