Give scientific reasons: Amniocentesis is used to diagnose genetic irregularities in an embryo or foetus.

(N/A) Amniocentesis is a prenatal diagnostic technique where amniotic fluid,which surrounds the developing foetus,is collected using a needle.
This fluid contains foetal cells that are shed during development.
These cells are analyzed for chromosomal abnormalities and genetic disorders using techniques like $DNA$ testing or karyotyping.
If a serious or incurable genetic disorder is detected,the parents may be advised to consider the termination of the pregnancy.
