Question

Which of the following cannot be detected in a developing fetus by amniocentesis?
A. Klinefelter syndrome
B. Paternity
C. Sex of the fetus
D. Jaundice

Answer 1

Hint: Amniocentesis is a very popular technique which means puncture of amnion from where amniotic fluid is collected. It can be defined as a medical procedure that is performed on pregnant women to diagnose chromosomal and genetic disorders of the fetus.

Complete step by step answer: Amniocentesis is employed to discover hereditary and protein abnormalities within the growing fetus. It may be defined as a process dispensed on expecting mothers to seek out anybody abnormalities or the sex of the unhatched kid during the time of pregnancy. During this antenatal process, a tiny low quantity of amniotic fluid is extracted from the amnion encompassing the fetus. The fluid contains a tiny low quantity of DNA. This deoxyribonucleic acid is then analyzed for genetic abnormalities. The genetic material additionally provides the biological sex of the fetus.
Let’s take a look at all the options to get the correct answer,
· Amniocentesis is a type of medical process in which an amniotic fluid sample is collected using a hollow needle inserted into the uterus, to detect abnormalities in the developing fetus based on the chromosomal pattern.
· Amniocentesis is used to diagnose genetic disorders like Klinefelter syndrome and Down syndrome. By using this process, we can determine the sex of the growing fetus but it is not permissible legally i.e. it is banned.
· Jaundice cannot be diagnosed in a developing fetus by the amniocentesis process because jaundice is not a genetic disorder it’s an infectious disease.
Hence, the correct answer is Jaundice which is option D.

Note: For performing amniocentesis first, a needle is inserted within the uterus which is a female internal reproductive organ through the abdominal muscles so into the amniotic cavity. Prenatal diagnosis ought to be performed between the fifteenth and twentieth weeks of the physiological condition at any time before it'll injure the fetus. The genetic abnormalities determined by this method embrace congenital abnormality, Trisomy 13, Trisomy 18, chromosome aneuploidies, Fragile X, ectoblast, or neural tube defects like a congenital anomaly, and rare, genetic metabolic disorders. The alternative ways for discerning the sex of the unhatched kid are – non-cellular fetal DNA testing, villus sampling, and obstetrical tomography. Polyhydramnios is a medical condition where there’s an accumulation of amniotic fluids within the sac.
