Amniocentesis is used to detect the :

Presence of certain genetic disorders

The correct answer is Option (2)- Presence of certain genetic disorders

Amniocentesis is a medical procedure used during pregnancy to diagnose certain genetic abnormalities or fetal infections, among other conditions. It involves the extraction of a small amount of amniotic fluid surrounding the fetus for analysis. However, amniocentesis is not used to test for disorders like malaria or typhoid. Instead, it is primarily employed to detect chromosomal abnormalities such as Down syndrome, haemoplilia, sickle-cell anemia, etc., or genetic disorders in the developing fetus.

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.

A statutory ban on using amniocentesis is specifically for sex determination in order to legally address the growing issue of female foeticide.
