Mode of Inheritance

Most people with down syndrome do no inherit this trait. It is a random abnormal arrangement in the reproductive cells of the parents.

In some cases a parent can be a carrier of these abnormal arrangement of chromosomes, but not have down syndrome. This would lead to the result of a child with down syndrome if that parent reproduces.

Effect on the Human Population

About 1 out of every 691 births, is the ratio for the risk of a child with down syndrome. in the world today 400,000 people are living with down syndrome. This can effect the human population because people with this condition cannot reproduce and have offspring.
