Why do people with Down Syndrome seem to have the same facial features?
82465
Its caused by the gene that causes down syndrome.  They normally will have round faces, small eyes, be short, with poochy abdomines and many other simulariaties to one another.  Hope this helps.  By the way the techincal term for what they look like is mongaloid

The children will not be "twins" (they will likely not look the same, though they may look similar in the way siblings do). This is because during meiosis, the genes in each haploid are random, from both parents.\n\nFor example, if both twin brothers had a dominant gene for black eyes and a recessive gene for green eyes, one twin might pass on a black eye gene to his child, while the other might pass on a green eye gene.

I'd think its down syndrome with a bordeline normal intellect level.

Its the same genetic make-up as any two brothers or two sisters. Since they develop from two different eggs fertilized by a sperm each

I agree(although I hate the word retard). People with a learning disability, particularly Down's Syndrome, seem to have such a sweet, uninhibited disposition about them. It's like they have never thrown up the same emotional walls as the rest of us. I take a good deal of inspiration from my dealings with them.\nBrave question by the way, nice one!

Short answer is they are idiots.  I see a human being the same as me, no matter their skin tone.

lebanese are classified between caucasian and mongoloid so there is a possibility of blond hair and blue eyes. probably not in a pure lebanese person though.

just look at any baby picture and that is what their baby looks like.  They all look the same.  This one will just have lips bigger than her face.

Sure, if a person has an extra copy of Chromosome 21 (trisomy 21) They are mostly likely someone who has Down Syndrome. There are many other instances of extra chromosomeos (Kleinfelder's syndrome, XXY syndrome, etc).

I'm not sure what exactly you mean? But if you are wanting to know similarities and that it depends on if they are identical or not. Some twins can have everything in common and look a like and some have nothing in common and don't look a like and just because they are identical doesn't mean that they will act alike as well. Twins are born at the same time yes but they are there own person if you get what I'm saying. My mom is a identical twin her and her sister hate each other and have nothing in common except they both lie. Twins also run every generation her her side of the family.

down's syndrome is a disease that results from gaining an extra autosome through nondisjunction.  It effects autosome 21.

CHILDREN WITH DOWN'S SYNDROME\n\nYes- but with all the support and resources they need- this takes additional strain off the class teacher and the child, we're all different and children with Down's syndrome are all different too, if children have additional educational needs they need to be given additional support not marginalised. Children with Down's syndrome are still children.

Most of the differences are behavioral more than just "looks." But there are differences that cannot be detected by human eye. There are computer programs to determine the differences between faces for example and research done in Britain showed that except a couple of them, all of the twins can only match up to 30%, most of the twins were way lower than that around 10%; meaning they look same to your eye, but actually they are not the same at all, not even close.

to be honest, you shouldnm't really worry about this kind of thing and not let it get to you. \nsome people who were born with defects would be alot happier to have two different eyes than some of the other misfortunes of genetics, such as being deaf, not being able to walk, blindness, missing limbs, etc. etc.\nif anything don't look at this thing as a defect think of it as something that is interesting about you. \nmany people have your same condition, so it's not that really big of a deal. \nbut if it really bugs you, see about getting contacts. and of course they don't need to be prisciption ones, you can just get a regular pair colored to whatever ever color you want.

Mental retardation is the most common and serious birth defect associated with FAS.  Perhaps the most notable defects in FAS involve the face and eyes. In general, these defects are obvious and include facial bone hypoplasia (under-development), a long, underdeveloped philtrum (the groove in the middle of the upper lip), a thin upper lip, a short nose, and ptosis (drooping of the eyelids). Although the typical facial features may not be as apparent during the newborn period, they become more prominent as the infant develops. As these children grow into young adulthood, however, the facial abnormalities become more subtle and thereby contribute to the difficulty of recognizing FAS in older persons. With these physical abnormalities come sensory deficits that frequently involve vision, hearing and speech. Hyperacusis (abnormal acuteness of hearing) is common in infants, and approximately one third of these infants have a conductive hearing loss and another one-third have a sensorineural hearing loss. More than 90 percent of infants with FAS have delays in receptive and expressive language development.

Sure it is,and it's a shame ! There was a study not long ago done on the exact reasons we deem one person attractive and the next not. It seems to have a lot to do with symetry...if both sides of your face are 'equal'. Examples of an 'equal' face would be Mel Gibson, the actor, or Cindy Crawford, the model. Their good looks are good looks to us because their faces are symetrical.  What a small thing to decide whether one is socially acceptable or not! What small people we are to judge folks by their looks, anyway! Look at Albert Einstein..no one would EVER accuse him of being physically attractive, yet look at what he accomplished for mankind! What was it Forrest Gump said all the time? Ugly is as ugly does??
