Quizplus · Accepted Answer

During amniocentesis, fetal fibroblasts in amniotic fluid are cultured and a karyotype is constructed. This involves examining the chromosomes of the fetal cells to check for any abnormalities in the number or structure of chromosomes. This procedure is commonly done to screen for genetic disorders such as Down syndrome or cystic fibrosis. The procedure involves inserting a needle through the mother's abdomen and into the amniotic sac, where a small amount of amniotic fluid is removed for testing.
