Questions

  1. 1.

    In human oogenesis, which event directly triggers the secondary oocyte to resume and complete its second meiotic division?

    • A) Penetration of the oocyte plasma membrane by a sperm cell
    • B) The mid-cycle surge of luteinizing hormone
    • C) Implantation of the developing blastocyst into the endometrium
    • D) Fusion of the haploid male and female pronuclei
  2. 2.

    During human spermatogenesis, which of the following cells represents the first haploid stage formed during the division process?

    • A) Spermatogonium
    • B) Primary spermatocyte
    • C) Secondary spermatocyte
    • D) Spermatid
  3. 3.

    Which of the following structural modifications occurs during spermiogenesis in human males?

    • A) Development of the acrosome from the Golgi apparatus and shedding of excess cytoplasm
    • B) Synapsis of homologous chromosomes and exchange of genetic material
    • C) Reduction of the chromosome number from diploid (2n) to haploid (n)
    • D) Mitotic proliferation of stem cells along the basement membrane of seminiferous tubules
  4. 4.

    In human female gametogenesis, at which stages of meiosis do the primary oocyte and the secondary oocyte pause their division, respectively?

    • A) Metaphase I and Prophase II
    • B) Anaphase I and Metaphase II
    • C) Prophase I and Metaphase II
    • D) Telophase I and Anaphase II
  5. 5.

    Which of the following statements correctly compares human spermatogenesis and oogenesis?

    • A) Spermatogenesis produces four functional haploid gametes from one primary spermatocyte, whereas oogenesis typically yields one functional ovum and polar bodies from one primary oocyte.
    • B) Both spermatogenesis and oogenesis begin exclusively at puberty and continue at an uninterrupted rate throughout an individual's entire life.
    • C) Primary oocytes complete meiosis II prior to ovulation, whereas secondary spermatocytes complete meiosis II only after fertilization occurs.
    • D) Cytokinesis divides cytoplasm equally among all daughter cells during both spermatogenesis and oogenesis to ensure uniform gamete size.
