Question

Quizplus · Accepted Answer

A teratogen is any substance, organism, or physical agent that can cause birth defects or abnormal development of a fetus. It includes drugs, chemicals, radiation, infections, and more. It is not the same as a genetic defect, which is an inherited abnormality in the DNA sequence. Cystic fibrosis and sickle-cell anemia are examples of genetic disorders, not teratogens.
