The answer to this question would be: Extra chromosomal material

Down syndrome is a genetic disease that caused by trisomy of chromosome 21. Trisomy means that the chromosome is having an extra pair, making a total of 3 chromosomes instead of 2. The disease will cause the child to have an intellectual disability. The primary risk factor for this disease would be old mother.
