1. Q1NEET 2026Hormones Secreted by the Placenta

   Which of the following hormone is not secreted by human placenta?

   • A. Estrogen
   • B. Progesterone
   • C. LH
   • D. hCG
   Show answer

   Answer: B — Progesterone

   The human placenta secretes estrogen, progesterone, human chorionic gonadotropin (hCG), and human placental lactogen (hPL). LH (Luteinizing Hormone) is secreted by the anterior pituitary gland, not the placenta.

2. Q2NEET 2026Sperm Structure and Motility

   Sperm motility is due to

   • A. ciliary movement
   • B. amoeboid movement
   • C. muscular movement
   • D. flagellar movement
   Show answer

   Answer: C — muscular movement

   Sperm motility is due to flagellar movement, as the sperm's tail is a flagellum that propels it forward.

3. Q3NEET 2026Layers Surrounding the Ovum

   The covering of ovum at ovulation is _______________.

   • A. zona radiata
   • B. zona pellucida
   • C. chorion
   • D. endometrium
   Show answer

   Answer: A — zona radiata

   At ovulation, the ovum (secondary oocyte) is surrounded by a thick, transparent, non-cellular layer called the zona pellucida.

4. Q4NEET 2026Male Reproductive System - Structures

   Which of the following structure is not a part of the male reproductive system?

   • A. Epididymis
   • B. Vasa efferentia
   • C. Infundibulum
   • D. Rete testis
   Show answer

   Answer: B — Vasa efferentia

   Infundibulum is the funnel-shaped opening of the fallopian tube (oviduct) near the ovary, and is part of the FEMALE reproductive system. Epididymis, vasa efferentia, and rete testis are all parts of the male reproductive system (the duct system associated with the testis).

5. Q5NEET 2026Menstrual Cycle - Ovulation and Corpus Luteum

   Given below are two statements: Statement I: Ovulation is caused by LH surge leading to rupture of Graafian follicles. Statement II: Graafian follicle remaining after ovulation transforms into corpus luteum and secretes large amount of estrogen. In the light of the above statements, choose the most appropriate answer from the options given below:

   • A. Both Statement I and Statement II are incorrect
   • B. Statement I is correct but Statement II is incorrect
   • C. Statement I is incorrect but Statement II is correct
   • D. Both Statement I and Statement II are correct
   Show answer

   Answer: A — Both Statement I and Statement II are incorrect

   Ovulation is indeed triggered by a surge in luteinizing hormone (LH), which causes rupture of the Graafian follicle and release of the ovum -- Statement I is correct. However, the corpus luteum (formed from the remaining follicle after ovulation) primarily secretes large amounts of PROGESTERONE, not estrogen -- Statement II is incorrect.

6. Q6NEET 2026Animals where haploid cells divide mitotically to produce gametes

   In which animal do haploid cells divide mitotically to produce gametes?

   • A. Male honeybees
   • B. Male grasshoppers
   • C. Male earthworms
   • D. Male frogs
   Show answer

   Answer: —

   In honeybees, males are haploid (from unfertilized eggs) and produce sperm via mitotic division of haploid cells, not meiosis.

7. Q7NEET 2026Matching embryonic development to months of pregnancy

   Match List I with List II related to embryonic development at various months of pregnancy: List I — A. The foetus movement starts and hair appears on the head, B. The foetus develops limbs and digits, C. The foetus develops external genital organs, D. The foetus body is covered with fine hair; eyelids and eyelashes are formed. List II — I. 24 weeks of pregnancy, II. 20 weeks of pregnancy, III. 8 weeks of pregnancy, IV. 12 weeks of pregnancy.

   • A. A-II, B-IV, C-III, D-I
   • B. A-IV, B-II, C-III, D-I
   • C. A-II, B-IV, C-I, D-III
   • D. A-I, B-IV, C-III, D-II
   Show answer

   Answer: A — A-II, B-IV, C-III, D-I

   Foetus movement/hair at 20 weeks (II); limbs/digits develop around 12 weeks (IV); external genital organs around 8 weeks (III); fine hair/eyelids/eyelashes around 24 weeks (I). A-II, B-IV, C-III, D-I.

8. Q8NEET 2026Correct statements about spermatogenesis

   Spermatogonia undergo a series of cell divisions to produce sperms. Select the correct statements from the following: A. Spermatogonia always undergo meiotic cell division. B. Primary spermatocytes divide mitotically to produce secondary spermatocytes. C. Secondary spermatocytes, through their second meiotic division, produce haploid spermatids. D. Spermatids produce spermatozoa through mitosis. E. Spermatids transform into spermatozoa by spermiogenesis.

   • A. A, C and E only
   • B. C and E only
   • C. A and E only
   • D. B and D only
   Show answer

   Answer: A — A, C and E only

   C (secondary spermatocytes undergo meiosis II to form spermatids) and E (spermiogenesis transforms spermatids to spermatozoa) are correct. A is false (spermatogonia divide mitotically first, then meiotically); B is false (primary spermatocytes divide meiotically, not mitotically); D is false (spermatids transform via spermiogenesis, not mitosis). C and E only.

9. Q9NEET 2026Incorrect statements about Rh grouping

   Select the incorrect statements with reference to Rh grouping. A. Erythroblastosis foetalis is a condition observed having foetus with Rh- blood and mother with Rh+ blood. B. Rh antigen is observed on RBCs in the majority of human beings. C. Before blood transfusion, Rh group should also be matched. D. Rh incompatibility is observed when a pregnant mother is Rh- and the foetus is Rh-. E. Erythroblastosis foetalis can be avoided by administering anti-Rh antibodies to the mother immediately after the delivery of the second child.

   • A. A and B only
   • B. C and D only
   • C. A and D only
   • D. B and C only
   Show answer

   Answer: B — C and D only

   A is incorrect (it's the reverse — Rh- mother with Rh+ foetus); D is incorrect (incompatibility occurs when mother is Rh- and foetus is Rh+, not Rh-); E is also inconsistent (antibodies given after first, not second, delivery) though per key, the correct selection of incorrect statements is A and D only.

10. Q10NEET 2025Sperm Structure

    Match List - I with List - II. List – I: A. Head, B. Middle piece, C. Acrosome, D. Tail. List-II: I. Enzymes, II. Sperm motility, III. Energy, IV. Genetic material. Choose the correct answer from the options given below:

    • A. A-IV, B-III, C-I, D-II
    • B. A-IV, B-III, C-II, D-I
    • C. A-III, B-IV, C-II, D-I
    • D. A-III, B-II, C-I, D-IV
    Show answer

    Answer: —

    Sperm head contains the nucleus with genetic material (IV). Middle piece has mitochondria that produce energy (III). Acrosome is filled with hydrolytic enzymes (I). Tail provides motility (II). So A-IV, B-III, C-I, D-II.
