what is amniocentesis?
Amniocentesis is a process by which amniotic fluid (fluid present inside the uterus surrounding the unborn baby) from the uterus of a pregnant lady is taken out by a needle to test the developmental abnormalities of the baby inside the mother’s womb.
This test can detect thalassemia, down’s syndrome, anemia and many other abnormalities before birth.
Amniocentesis is a medical procedure used in prenatal diagnosis of chromosomal abnormalities and fetal infections,in which a small amount of amniotic fluid, which contains fetal tissues, is sampled from the amnion or amniotic sac surrounding a developing fetus, and the fetal DNA is examined for genetic abnormalities. It is the sampling of amniotic fluid using a hollow needle inserted into the uterus, to screen for developmental abnormalities in a fetus.
in the ncert book, where projects are assigned this question was given!
over there there was a single line regarding amniocentesis!
Aniocentesis was a technique to identify chromosomal abnoralities! But later when people started using it for finding out the gender of the unborn child which resulted in the foeticide of women child before birth, it was banned.
Amniocentesis is a technique or method of determining inherited or genetic diseases in developing foetus.
In womb foetus is surrounded by fluid called amniotic fluid on its all sides. A very small portion of this fluid is withdrawn from the abdomen of pregnant women with the help of thin needle and then, tested for various diseases like sickle cell anemia, enzymes deficiency etc.
