8. Amniocentesis for sex determination is banned in our country. Is this ban necessary? Comment.

Ans: Amniocentesis is a pre-natal diagnostic technique that is used to determine the sex and metabolic disorders of the developing foetus in the mother’s uterus through the observation of the chromosomal patterns.

This method was developed so as to determine any kind of genetic disorder present in the foetus.

Thus, to prevent the increasing female foeticides, it is necessary to ban the usage of amniocentesis technique for determining the sex of a child.
