It's when a child is neglected as a child
No age group is affected; Down syndrome is a chromosome condition that is with you at birth.

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
Chromosome 21 is tripled in Down syndrome.
No. Parents who have a child with Down syndrome do not have an increased chance in having another child with Down syndrome. Everyone has the same chance of having a child with Down syndrome, 1%.
The lungs.
That would mean that the mother is the one with Down syndrome, since men with Down syndrome are sterile. There is a 50% chance that the child will have Down syndrome and 50% chance that child will be born without.

The proportion of men to women with Down syndrome is about equal.
No Marie does not have a child with down syndrome. It was mistaken that she did because one of her children is crossed eyed.
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.
