Down syndrome is caused by an extra copy of chromosome 21, which occurs during the formation of reproductive cells (eggs and sperm) or during early fetal development. This extra copy of genetic material can lead to physical and developmental differences.
Yes, the risk of having a child with Down syndrome increases with maternal age. This is because as a woman gets older, there is a higher chance of errors occurring during the formation of reproductive cells.
Currently, there is no known way to prevent Down syndrome. It is a genetic condition that occurs by chance and cannot be prevented.
No, Down syndrome is not caused by environmental factors. It is a genetic condition that occurs randomly and is not influenced by a mother's diet, lifestyle, or exposure to toxins.
No, there is no evidence to suggest that a mother's health during pregnancy has any impact on the development of Down syndrome in her child. It is a genetic condition that occurs before or during conception.
