Which of the following cannot be detected in a developing foetus by amniocentesis?

Jaundice

The correct answer is Option (1)- Jaundice

Amniocentesis is a medical procedure in which a small amount of amniotic fluid surrounding a developing fetus in the uterus is extracted using a needle inserted through the abdomen.

The collected amniotic fluid contains fetal cells, which are analyzed to obtain genetic information about the fetus. These cells can be used for various diagnostic purposes

The use of amniocentesis for prenatal sex determination purposes is illegal. The primary reason for restricting amniocentesis and similar prenatal diagnostic techniques is to prevent the practice of sex-selective abortions.

In aminocentesis some of the amniotic fluid of the developing foetus is taken to analyse the fetal cells and dissolved substances. This procedure is used to test for the presence of certain genetic disorders such as, down syndrome, haemoplilia, sickle-cell anemia, etc., determine the survivability of the foetus.

Among the options provided, "Jaundice" is not a condition typically detected through amniocentesis. Jaundice is not a genetic disease, so cannot be detected by amniocentesis.
