What is the primary characteristic of the animal life cycle Figure 13.6a regarding haploid cells?

  • A: Haploid cells undergo mitosis to form a multicellular organism.
  • B: The gametes are the only haploid cells, and they do not undergo further cell division before fertilization.
  • C: Meiosis occurs in the diploid zygote immediately after fertilization.
  • D: Both the diploid and haploid stages are multicellular.

Explanation

The text explicitly states for the animal life cycle: 'gametes are the only haploid cells. Meiosis occurs in germ cells during the production of gametes, which undergo no further cell division prior to fertilization.'
