Gametogenesis is part of the Embryology section of Anatomy. Practise 10 exam-style MCQs for NEET PG, FMGE, INI-CET and NEET SS, each with the correct answer and a detailed explanation.
Gametogenesis MCQs explore how primary oocytes pause in meiosis until puberty, how spermatogenesis unfolds over roughly ten weeks, and how capacitation and the acrosome reaction prepare sperm for fertilisation — high-yield NEET PG revision from first principles.
Sample Gametogenesis MCQs with answers
Sample MCQ #1
Which of the following cells remain dormant in the ovary until puberty?
APrimordial germ cell
BPrimary oocyte
CSecondary oocyte
DFirst polar body
Show Answer & Explanation ▾
✓ Correct Answer: B. Primary oocyte
Primary oocytes remain dormant in the ovary until puberty. They are arrested in prophase (dipytotene/diplotene) of meiosis I and surrounded by flat epithelial cells (primordial follicles) in the ovary before puberty.

Sample MCQ #2
Spermatogenesis is completed in approximately how many days?
A54
B94
C24
D74
Show Answer & Explanation ▾
✓ Correct Answer: D. 74
Spermatogenesis is completed in approximately 74 days. Spermatogenesis covers the entire process of sperm formation from spermatogonia into spermatozoa. Spermiogenesis covers the process of transformation from spermatid into spermatozoa. Reference - Textbook of Langman's, 12th Edition, General Embryology Page number - 32
Sample MCQ #3
Which stage of spermatogenesis is characterized by an independent assortment of maternal and paternal chromosomes?
ASpermatogonia to primary spermatocyte
BPrimary spermatocyte to secondary spermatocyte
CSecondary spermatocyte to spermatid
DSpermatid to spermatozoa
Show Answer & Explanation ▾
✓ Correct Answer: B. Primary spermatocyte to secondary spermatocyte
Independent assortment is the random distribution of chromosomes. It takes place during meiosis I where there is division from primary spermatocyte to secondary spermatocyte. The law of independent assortment states that alleles for separate traits are passed independently of one another into the gametes.

Sample MCQ #4
Before a spermatozoan can fertilize an ovum:
AThe cell membrane is removed from the spermatozoan head
BThe zona pellucida must be shed
CThe acrosomal membrane must perforate
DThe tailpiece is lost
Show Answer & Explanation ▾
✓ Correct Answer: C. The acrosomal membrane must perforate
Capacitation, in which a glycoprotein coat is shed from the sperm head, and the acrosome reaction, in which the acrosomal membrane perforates, must occur for fertilization to take place. Zona pellucida is not lost until after the fourth day of development. Decidua reaction occurs after fertilization. Reference - Textbook of Langman's, 12th Edition, General Embryology Page number - 29
Sample MCQ #5
An infertile couple walked into IVF clinic. FSH analogs were injected to induce follicular growth and hCG was injected to induce final oocyte maturation. The oocyte was then retrieved transvaginally. The oocyte thus retrieved is arrested at which of the following stages?
AProphase of meiosis i
BProphase of meiosis ii
CMetaphase of meiosis i
DMetaphase of meiosis ii
Show Answer & Explanation ▾
✓ Correct Answer: D. Metaphase of meiosis ii
The oocyte retrieved after final maturation is the secondary oocyte that is arrested in metaphase of meiosis Il. If there is no fertilization, the secondary oocyte fails to complete the second meiotic division and degenerates about 24 hours after ovulation. In in-vitro fertilization, initially, FSH analogs are administered to induce follicular growth. At this stage, the oocyte is arrested in the prophase stage of meiosis I. The final maturation of the oocyte is induced by the administration of hCG. This causes the oocyte to resume the meiotic division, complete meiosis I, and enter meiosis II. However, the oocyte is arrested in the metaphase of meiosis Il until fertilization. Reference - Textbook of Langman's, 12th Edition, General Embryology Page number - 32
Sample MCQ #6
What is the timing of the origin of the primordial germ cells from epiblast?
A2 week of embryonic development
B4 week of embryonic development
C6 week of embryonic development
D8 week of embryonic development
Show Answer & Explanation ▾
✓ Correct Answer: A. 2 week of embryonic development
Primordial germ cells originate in the epiblast, during the 2nd week of development. Primordial germ cells (PGCs) are also known as primitive sex cells. During the 2nd week of development, they originate in the epiblast at the caudal end of the primitive streak. Reference - Textbook of Langman's, 12th Edition, General Embryology Page number - 32
Sample MCQ #7
Which organelle gives rise to the acrosomal cap of the sperm?
ANucleus
BGolgi apparatus
CCentrosome
DMitochondria
Show Answer & Explanation ▾
✓ Correct Answer: B. Golgi apparatus
The acrosomal cap of the sperm is derived from the Golgi apparatus. Reference - Textbook of Langman's, 12th Edition, General Embryology Page number - 32
