Which physical trait is commonly associated with Down Syndrome?

The physical trait commonly associated with Down Syndrome is a distinct facial appearance. Individuals with Down Syndrome often exhibit a specific set of facial characteristics that may include a flatter facial profile, almond-shaped eyes, a smaller nose, and a protruding tongue. These unique features are a result of the genetic differences associated with the condition, specifically the presence of an extra copy of chromosome 21.

While other physical traits like short stature can also be seen in individuals with Down Syndrome, the distinct facial appearance is the most recognized and associated hallmark of the condition. This characteristic is not only significant in identifying and diagnosing Down Syndrome but also plays a role in how the public perceives and interacts with individuals with this genetic condition.
