In context of amniocentesis, which of the following statement is incorrect?
Amniocentesis detects chromosomal/genetic disorders, not structural defects like cleft palate.
In amniocentesis, amniotic fluid is collected from the developing foetus to detect genetic disorders like Down syndrome and haemophilia, and survivability of the foetus, between 14–16 weeks of pregnancy.
It is not used to determine cleft palate, which can be detected by sonography.

Which of the following cannot be detected in a developing foetus by amniocentesis?Amniocentesis analyses foetal cells from the amniotic fluid for chromosomal patterns, so it detects sex and disorders such as Down and Klinefelter syndromes.
Jaundice is not a chromosomal or genetic disorder and cannot be detected this way.

The permissible use of the technique amniocentesis is forIn amniocentesis a small amount of amniotic fluid surrounding the developing foetus is withdrawn.
The foetal cells and dissolved substances in it are analysed to detect genetic disorders such as Down's syndrome, haemophilia and sickle-cell anaemia, and to judge the survivability of the foetus.
The same test can reveal the sex of the foetus from its chromosome pattern, and it was misused for female foeticide; sex determination by this technique is therefore statutorily banned.
It has nothing to do with artificial insemination or embryo transfer.
Hence the permissible use of amniocentesis is for detecting any genetic abnormality.
