A. diploid stage (2n) b. meiosis c. fertilization d. haploid stage (n) e. mitosis 2. Human cells spend most of their life cycles in a diploid stage, with only a selected number of cells undergoing meiosis to become haploid. Other organisms spend most of their life cycles in the haploid stage. Look ahead in this text to figures 28.14, 29.13, 29.15, and 30.10. Which of these organisms has a life cycle that is primarily haploid?
