Question

Quizplus · Accepted Answer

Trisomy 21 is another name for Down Syndrome, which is a genetic disorder caused by the presence of three copies of chromosome 21 instead of the usual two. This results in intellectual disability, distinct physical features, and an increased risk for certain health problems. Tay Sachs, triple-X syndrome, cystic fibrosis, and hemophilia are different genetic disorders caused by mutations in specific genes or chromosomes, and are not related to Trisomy 21 or Down Syndrome.
