An individual with Down syndrome has the presence of all or part of an extra 21st chromosome.
The different between males and females karyotype is that female has xx and male has xy.
Down Syndrome is the state of having one extra chromasome.
If you do not have down syndrome you have 46 chromosomes. Perfect pairs of each one. In Down syndrome you have an extra 21st chromosome. so 47 chromosomes total
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.
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.
Without the difference between scalars and vectors the Universe doesn't work !
Chromosomes are are your genetic material. Without them you would not exist.
Meiosis 1 is the process of separating chromosomes (independent assortment). Independent assortment is the random assortment of chromosomes. So without meiosis, there would be no way to separate the chromosomes randomly. Hope that helps(:
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.
