Amniocentesis is a technique used for some specific purpose. Can you list down its uses? Also, in spite of being useful, there is a statutory ban on amniocentesis. Give reasons to justify the ban.

Uses of amniocentesis are:
To legally check female foeticide or misuse of sex determination techniques.
To detect abnormal chromosomes, i.e., a genetic disorder.

Justification for ban:
To prevent female foeticide and thereby to prevent the change in the sex ratio of the population.
