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

Anaemia

The correct answer is Option (2) →Anaemia

A statutory ban on using amniocentesis is specifically for sex determination in order to legally address the growing issue of female foeticide. In some countries, particularly where there's a severe problem of female foeticide or gender-based abortions, legislation has been enacted to prohibit using prenatal diagnostic techniques, including amniocentesis, solely for determining the sex of the fetus.

Amniocentesis is a prenatal diagnostic procedure used to detect genetic and chromosomal disorders in a developing fetus by analyzing the amniotic fluid. Conditions like Down syndrome, sickle-cell anemia, and haemophilia, which are related to genetic or chromosomal abnormalities, can be detected through this procedure. However, anaemia, which is typically a condition involving low red blood cell count or hemoglobin, is not a genetic disorder and therefore cannot be detected by amniocentesis.
