This quiz covers embryology, focusing on genetic influences, developmental processes during pregnancy, and related medical advice.
She is young and has been taking folic acid so her baby is most likely completely normal
She should terminate the fetus and not have children
She is at no increased risk because she is otherwise healthy and has no other risk factors
She is at no increased risk because she is under 35 and the father's family has no history of neural tube defects
She is high risk and should have the baby evaluated using prenatal screening techniques
