What Procedure is Used to Obtain Embryonic or Fetal Chromosomes

Question

What procedure is used to obtain embryonic or fetal chromosomes for karyotyping?
A)Chorionic villi sampling (CVS)
B)Ultrasonography
C)Amniocentesis
D)Both chorionic villi sampling (CVS)or amniocentesis are used

Accepted Answer

Both chorionic villi sampling (CVS) and amniocentesis are procedures used to obtain embryonic or fetal chromosomes for karyotyping. CVS involves taking a small sample of the placental tissue, while amniocentesis involves taking a sample of the amniotic fluid surrounding the fetus. Both procedures carry some risks, so the decision to undergo them is typically made based on the individual circumstances of the pregnancy.
