The genetics behind the disease of DownSyndrome, DownSyndrome is passed down through the parents, each parent gives half of his/her chromosomes to the child. A parent that have a child that has DownSyndrome is passed from a parent that already has some type of syndrome or disease. There are many types of syndromes related to DownSyndrome, about 95% of people with DownSyndrome have trisomy 21 which means each cell in the body has 3 seperate copies of chromosome 21 instead of the usual 2 copies. Translocation DownSyndrome is about 3% of people who have this this occurs when an extra part or a whole extra chromosome 21 is present but is attached to a different chromosome rather than being seperate. DownSyndrome is neither dominate or rssesive this occurs when the creation of sperm or egg cells (meiosis) does not occur properly.

The quality of life if you have DownSyndrome is much the same but then need special treatment and help along their life. Treatment that can help assist DownSyndrome people is self care which is like physical exercise, special education like learning with a prac teacher speech therapy and support groups.
