Question

Quizplus · Accepted Answer

Chorionic villus sampling (CVS) is a prenatal test in which a sample of placental tissue is removed and analyzed to detect chromosomal abnormalities and genetic disorders. This is done by inserting a needle or tube through the mother's cervix or abdomen to obtain a small sample of the chorionic villi, which are finger-like projections on the placenta that contain fetal cells. Amniocentesis is a different type of prenatal test that involves removing a sample of amniotic fluid, while karyotyping is a laboratory technique used to analyze chromosomes. Pedigree is a graphical representation of inherited traits in a family but is not a method of obtaining placental tissue samples.
