Question
Why do fetuses have chromosome abnormalities?
Answer
The causes of fetal chromosome abnormalities may include factors such as hereditary transmission across generations, as well as infections, medications, and environmental factors. Common abnormalities include numerical and structural anomalies, with trisomies being the most common, such as trisomy 13, 16, 18, 21, and 22. If a fetal chromosome abnormality is diagnosed, it is recommended to terminate the pregnancy.
