NEET 2016 Phase 1 · BiologyPrevious Year Question

In context of Amniocentesis, which of the following statement is incorrect?

Answer: (D) It can be used for detection of Cleft palate. Answer: (d) It can be used for detection of Cleft palate Solution: Amniocentesis analyses fetal cells and dissolved substances in the amniotic fluid to detect chromosomal/genetic disorders such as Down syndrome, haemophilia and sickle-cell anaemia — it cannot detect cleft palate, a structural malformation, so statement (4) is incorrect.

  1. A.It is usually done when a woman is between 14 – 16 weeks pregnant
  2. B.It is used for prenatal sex determination
  3. C.It can be used for detection of Down syndrome
  4. D.It can be used for detection of Cleft palate

Correct Answer

(D) It can be used for detection of Cleft palate

Solution & Explanation

Answer: (d) It can be used for detection of Cleft palate Solution: Amniocentesis analyses fetal cells and dissolved substances in the amniotic fluid to detect chromosomal/genetic disorders such as Down syndrome, haemophilia and sickle-cell anaemia — it cannot detect cleft palate, a structural malformation, so statement (4) is incorrect. Although it can reveal the foetus's sex, this misuse for prenatal sex-determination is statutorily banned but technically possible, so (2) is a correct statement. Statements (1) and (3) describe genuine, correct uses of the test. NCERT Reference: Reproductive Health, p.42 — "This procedure is used to test for the presence of certain genetic disorders such as, down syndrome, haemoplilia, sickle-cell anemia, etc."
