Question #45551
The Question
A pregnant woman at 22 weeks of gestation undergoes amniocentesis, revealing a fetal karyotype of 45, XO. The couple requests a Medical Termination of Pregnancy (MTP). Which of the following statements correctly integrates the biological diagnosis with the regulatory parameters of the MTP (Amendment) Act, 2021?
Options
- A.
The fetus has Klinefelter's syndrome, a viable autosomal aneuploidy; hence MTP is strictly prohibited after 20 weeks as the condition is not life-threatening.
- B.
The fetus has Turner's syndrome, a viable sex chromosomal monosomy; MTP can be authorized by two registered medical practitioners under the clause of substantial fetal abnormality.
- C.
The karyotype indicates a lethal autosomal monosomy; therefore, MTP is permitted at any gestational age without medical practitioner approval due to absolute fetal non-viability.
- D.
The fetus has Turner's syndrome; however, since the pregnancy has crossed the 20-week threshold, termination legally requires the direct authorization of a State-level Medical Board.

Why This Question Is Tricky
Common Mistakes
This question requires cross-chapter synthesis between 'Principles of Inheritance' and 'Reproductive Health'.
The conceptual pivot lies in correctly identifying 45, XO as a viable sex chromosomal aneuploidy (Turner's syndrome) rather than a lethal autosomal defect, and accurately applying the gestational timeframes of the MTP (Amendment) Act, 2021 (specifically the 20-24 week window requiring two RMPs vs. the >24 week window requiring a Medical Board).
