Questions and Answers
Which statement regarding oogenesis is true?
Which statement regarding oogenesis is true?
- Primary oocytes are released during ovulation.
- It produces one egg cell with three polar bodies. (correct)
- It involves reduction division and recombination.
- It produces four genetically varied gametes.
What is the main difference between spermatogenesis and oogenesis?
What is the main difference between spermatogenesis and oogenesis?
- Spermatogenesis produces four haploid sperm cells, while oogenesis produces one egg cell with three polar bodies. (correct)
- Spermatogenesis and oogenesis are the same process with no differences.
- Spermatogenesis produces one sperm cell with three polar bodies, while oogenesis produces four haploid egg cells.
- Spermatogenesis involves reduction division and recombination, while oogenesis involves doubling, pairing, and separation of homologues.

Study Notes
- Gametes are haploid while somatic cells are diploid.
- Meiosis results in reduction division and recombination.
- Reducing the number of chromosomes prevents doubling in every generation.
- Meiosis I involves reduction division and recombination, while Meiosis II forms gametes.
- Prophase I involves unique genetic combinations.
- Metaphase I involves lining up homologous pairs, and Anaphase I causes chromosome separation.
- Meiosis produces four genetically varied gametes.
- Spermatogenesis produces four haploid sperm cells, while oogenesis produces one egg cell with three polar bodies.
- Primary oocytes remain stuck in Prophase I until puberty.
- Sperm formation involves doubling, pairing, and separation of homologues.
