Chapter 23/24 Quiz Hints

1. Make sure you know the three sources of variation due to sexual reproduction.
Pay particular attention to independent assortment and crossing over. Be able to explain and possibly illustrate them with a little drawing. (hint, hint. . .!)

2. Make sure you know the definition of species as given by the Biological Species Concept.

3. Know the difference between allopatric and sympatric speciation- the basic difference. Know the word derivations.

4. Be able to list and give an example of each of the reproductive isolating mechanisms (prezygotic and postzygotic). You will need to look in the book for this since I didn’t go into detail in my lecture notes. See pages 447-448. Know these well since this is free response question #4 and therefore could be a quiz question!
