An individual with Down syndrome has the presence of all or part of an extra 21st chromosome.
downs syndrome is a a chromosome abnormality in which their is an extra copy of the 21st chromosome causing the person to have a flatter face slanted eyes and a mental handicap.
In Down syndrome, a person's cells have an extra copy of chromosome 21. In other words, instead of a pair of chromosomes, a person with down syndrome has three of that chromosome. Down syndrome most often occurs when chromosomes fail to separate properly during meiosis. People with down syndrome have a degree of mental retardation. Heart defects are also common, but can be treated.

What is the difference between the population and sample regression functions? Is this a distinction without difference?
Without a decimal, there is no difference.
Without the difference between scalars and vectors the Universe doesn't work !
People with down syndrome has an extra chromosome in the 21st pair. The normal amount of chromosomes is 56 single chromosomes (23 pairs). A person with down syndrome has 57 chromosomes. Therefore, they look and act more different than people without the disorder. Instead of looking like their parents, people with down syndrome look more like other people who has down syndrome.
Yes, you can have Asperger Syndrome when you're an adult.Asperger Syndrome is no longer a diagnosis, it has been merged with Autism - the two are the same, the only difference was that Asperger Syndrome was given to those who were Autistic but without developmental delays in childhood, not enough to be a separate diagnosis. You are born Autistic and you continue to be Autistic throughout your entire life, Autism is a difference in your brain and your brain doesn't change to that of a neurotypical person once you enter adulthood.
Humans without a disorder will have 23 pairs of chromosomes. However, there are many disorders caused by different numbers of chromosomes. For example, Trisomy 21 (Down Syndrome) is a disorder caused by the presence of an extra chromosome 21.
