Why do people with down syndrome look the same?

Question

I have never understood why, but there face structure seems the same.

Answer 1

Down's syndrome is a genetic disorder that was
established at the moment of conception. Normally, there are 23 pairs of
chromosomes that make up the fertilized egg. One of each pair is from
the sperm and the other from the egg. In Down's there is an extra
chromosome 21. The medical term is trisomy 21. This is the usual reason
for Down's syndrome.

The most obvious consequences of having an extra chromosome 21 are
an epicanthal fold around the eyes, short stature, dental deformities,
broad chest and mental retardation. The epicanthal fold about the eyes
give them an Asiatic or Mongolian appearance, hence, the older term
mongoloid.

Answer 2

It's because of the way your brain works. The brain performs facial recognition in a manner somewhat like rembering a charicature of the face. The thing is, the brain stores enough information to distinguish the face from all faces seen so far, not from all faces. Thus down's syndrome sufferers look the same for the same reason that all black people looked the same to the westerners who first saw them, the brain just remember characteristic of downs syndrome as characteristics of that persons face.

Answer 3

Many genetic disorders have features that are unique to them and manifest in all those that have the active genes. It is just an outward physical manifestation of the genes that cause inward mental changes as well. Just part of it.
