Answer 1

What Causes Down Syndrome?

Normally, at the time of conception a baby inherits genetic information from its parents in the form of 46 chromosomes: 23 from the mother and 23 from the father. In most cases of Down syndrome, however, a child gets an extra chromosome - for a total of 47 chromosomes instead of 46. It's this extra genetic material that causes the physical and cognitive delays associated with DS.

Although no one knows for sure why DS occurs and there's no way to prevent the chromosomal error that causes it, scientists do know that women age 35 and older have a significantly higher risk of having a child with the condition. At age 30, for example, a woman has less than a 1 in 1,000 chance of conceiving a child with DS. Those odds increase to 1 in 400 by age 35. By 42, it jumps to about 1 in 60.

Answer 3

In 99% of the cases, no. There is one rare case that is inherited from a parent carrying it.

The biggest risk factor is your age - the older you are, the greater the risk. It's pretty small until you reach about 40 though. At age 22 your odds are really really low.

Answer 4

NO..it happens when the cells start splitting and its an "accident" when chromosome 21 breaks off giving you an extra chromosome which is called Down Syndrome or Trisomy 21....Good Luck!

Answer 5

nope not at all, it all comes down to your age and the risk.. if you have the gene then the risk of course will be higher but hey you will never know unless you go for your downs test at around 12 weeks of pregnancy.

Answer 6

No, it's from an extra chromosome.

Answer 7

No.

Answer 8

no.
