Which of the following is a common physical characteristic associated with Down syndrome?

The choice indicating small noses and stubby fingers accurately reflects common physical characteristics associated with Down syndrome. Individuals with Down syndrome often exhibit distinct facial features, which can include a flat facial profile, a small nose, and shorter fingers that may appear broader and more stubby compared to the typical population. These characteristics arise from the genetic variations associated with the condition, specifically an extra copy of chromosome 21.

Understanding the specific features associated with Down syndrome is important for awareness and support, as these traits can influence both physical development and social interactions. The other options list characteristics that are not typically associated with Down syndrome and reflect different conditions or traits. For instance, long limbs and high muscle tone are not commonly observed in individuals with Down syndrome, while large heads and big ears do not accurately represent the classic physical appearance associated with the syndrome.
