Explain the significance of reproductive isolating mechanisms and distinguish among the various prezygotic and postzygotic barriers.
Write the definition of the following terms:
1. Semelparous life history
2. Iterous species
3. Senescence
4. Antagonistic pleiotropy
5. Carrying capacity
What is the Red Queen Dynamic? Using the snail example, explain why different parasite and host genotypes are expected to oscillate in frequency? Why would this favor sexual reproduction or outcrossing?

The following questions could help answer the question above. What are the advantages of sexual reproduction? What are the disadvantages? How do traits selected by sexual selection and those selected by differential survival mix in an animal species? i.e. is it more important to mate or survive? Use specific examples to illustrate your point. Your answers should indicate an understanding of the mechanism behind natural selection.
