What can cause chromosomal abnormalities in a fetus?

What increases the risk of chromosomal abnormalities?
Several factors increase the risk of having a baby with a chromosomal abnormality: Woman’s age: The risk of having a baby with Down syndrome increases with a woman’s age—steeply after age 35. Family history: Having a family history (including the couple’s children) of a chromosomal abnormality increases the risk.
Can birth defects that are hereditary be prevented?
The mother or father may pass on genetic abnormalities to their baby. Genetic abnormalities occur when a gene becomes flawed due to a mutation, or change. In some cases, a gene or part of a gene might be missing. These defects happen at conception and often can’t be prevented.
How can we prevent those abnormalities caused by mutations?
To avoid mutations, we need to limit exposure to these chemicals by using protective equipment, like masks and gloves, when working with them. Once these chemicals are no longer being used, they should be properly disposed of (see Table 1).

Why do chromosomal abnormalities occur?
Some chromosomal conditions are caused by changes in the number of chromosomes. These changes are not inherited, but occur as random events during the formation of reproductive cells (eggs and sperm). An error in cell division called nondisjunction results in reproductive cells with an abnormal number of chromosomes.
What is the most common chromosomal abnormality resulting in birth defects?
Down syndrome, on the other hand, is by far the most common chromosomal abnormality, affecting 1 in 800 babies. The risk of having a child with this condition increases with maternal age, rising exponentially after a woman reaches age 35.
