Chapter 13

1. Explain why organisms only reproduce their own kind, and why offspring more closely resemble their parents than unrelated individuals of the same species.
2. Explain what makes heredity possible.
3. Distinguish between asexual and sexual reproduction.
4. Diagram the human life cycle and indicate where in the human body that mitosis and meiosis occur; which cells are the result of meiosis and mitosis; and which cells are haploid.
5. Distinguish among the life cycle patterns of animals, fungi, and plants.
6. List the phases of meiosis I and meiosis II and describe the events characteristic of each phase.
7. Recognize the phases of meiosis from diagrams or micrographs.
9. Describe the process of synapsis during prophase I, and explain how genetic recombination occurs.
10. Describe key differences between mitosis and meiosis; explain how the end result of meiosis differs from that of mitosis.
11. Explain how independent assortment, crossing over, and random fertilization contribute to genetic variation in sexually reproducing organisms.
12. Explain why inheritable variation was crucial to Darwin's theory of evolution.
13. List the sources of genetic variation.
