Quizplus · Accepted Answer

Cystic fibrosis is not associated with the chromosome involved in Down syndrome. Down syndrome is caused by an extra copy of chromosome 21, while cystic fibrosis is caused by mutations in the CFTR gene located on chromosome 7. The other traits (increased incidence of leukemia, cataracts, mental retardation, and accelerated aging) are all associated with Down syndrome.
