As the disease is genetic, DS women have nearly a 50% chance of passing on DS to their offspring if the father does not have DS.
No, because people with Down syndrome can't have children.
Down's Syndrome is caused mainly by a mutation in the gene. It is a genetic disorder, which means it was passed on from parents to offspring.
No.
No. Parents of Down Syndrome typically are normal genetically and there is no test for parents to determine the possibility of a Down Syndrome offspring. There are no known external factors that are known to contribute to Down Syndrome. It is possible to test for Down Syndrome in the fetus.
INHERITED for A~plus
Nondisjunction.
it's a genetic trait that is passed down from the parent to there offspring.
The alleles that are passed from parents to offspring
Mutations can be passed from parent to offspring only by mutations found in genes. These genetic mutations can be hereditary. Chromosomal mutations only occur in one person and cannot be passed on to the offspring.
That depends. Men with Down syndrome have been shown to be sterile, while women with Down syndrome are capable of carrying a child, with 50% likelihood that the child will be born with Down syndrome.
Disorders, such as Down's Syndrome, are caused by nondisjunction.
Yes two non-Down syndrome parents can have a Down syndrome child. This is the most common situation, mainly because very few Down syndrome affected people are parents. Few Down Syndrome affected people become parents, partly because of reduced fertility associated with the syndrome, partly because of an increased risk of passing on the syndrome (very roughly from 1 in 800 to 1 in 3), and partly because of societal restrictions. ___________ Also, the parent(s) who has 1 down syndrome gene will be passed onto the child
