![Picture](/uploads/5/0/6/7/50672819/8128096.png?250)
This is a sample pedigree showing how Down syndrome could be inherited through a family. The father in the first generation had Down syndrome. Because of this, three children in the second generation and three in the third generation also have the disorder.
DNA plays an important role in the inheritance of Down syndrome. This is because the children of people with Down syndrome are more likely to have it themselves. Most people with Down syndrome do not have children, but the ones who do have a higher chance of having a child with Down syndrome.
