CHAPTER

12

MEIOSIS AND SEXUAL LIFE CYCLES

OUTLINE
I. II. III. IV. Offspring acquire genes from parents by inheriting chromosomes Like begets like, more or less: a comparison of asexual versus sexual reproduction Fertilization and meiosis alternate in sexual life cycles: an overview Meiosis reduces chromosome number from diploid to haploid: a closer look
A. B. The Stages of Meiotic Cell Division A Comparison of Mitosis and Meiosis

V.

Sexual life cycles produce genetic variation among offspring
A. B. C. Independent Assortment of Chromosomes Crossing Over Random Fertilization

VI.

Evolutionary adaptation depends on a population’s genetic variation

OBJECTIVES
After reading this chapter and attending lecture, the student should be able to: 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. Distinguish sporophyte from gametophyte, and explain how plant life cycles differ from those of animals and fungi.

Meiosis and Sexual Life Cycles

List the phases of meiosis I and meiosis II and describe the events characteristic of each phase. Recognize the phases of meiosis from diagrams or micrographs. Describe the process of synapsis during prophase I and explain how genetic recombination occurs. Describe key differences between mitosis and meiosis; explain how the end result of meiosis differs from that of mitosis. Compare the phases of meiosis I with mitosis and distinguish between the chromosomal arrangement during metaphase of both processes....
