Answer to Question 1

A

Answer to Question 2

Amniocentesis involves inserting a large, hollow needle into the amniotic sac to obtain fetal body cells for analysis; CVS obtains fetal cells by catheterization through the cervix. Each can detect chromosomal abnormalities as well as many recessive abnormalities and diseases. However, amniocentesis cannot be carried out until early in the second trimester of the pregnancy (the 11th to 14th week, at the earliest), whereas CVS can be carried out just after the end of the embryonic stage (ninth week). The results from an amniocentesis are generally not available until two weeks after the procedure has been completed; the results from a CVS procedure may be available within 24 hours. Ultrasound is a sonar-like scanning of the fetus without the risk of infection, etc., associated with the other two methods. But ultrasound can only detect gross physical abnormalities (i.e., as indicated by the shape of the fetus).
