This was a delightful read.
The point was really clear.

Amniocentesis is a procedure performed during the second trimester of pregnancy and it can be used to detect genetic abnormalities. The amniotic fluid is taken from the woman's uterus and analyzed.
Though risks exist, they are not much. It is also an optional test, especially if the woman is above 35 and has another baby with a genetic disorder.

Thank you @zoestrong
Very clear illustration.
