There are three different types of Down syndrome: Standard Trisomy 21, Translocation, and Mosaicism. Standard Trisomy 21 is when the extra chromosome 21 comes from either the egg or sperm cell. Between 90% and 95% of all Down syndrome is Standard Trisomy 21.

Examples of genetic disorders?
There's many different genetic disorders such as: Down Syndrom Canavan Disease Muenke Syndrome Bloom Syndrome etc
How are the cells of a person with Down syndrome different from those of a person without Down syndrome?
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 genetic disorder for having three 21 chromosomes?
down syndrome
What are the stages of Down syndrome?
There are three different kinds of Down syndrome: Translocation, Trisomy 21, and Mosaic.Translation: occurs when a piece of chromosome breaks off and attaches to another.Trisomy 21 (the most common kind): caused by meiotic disjunction, or in other words a gamete produces an extra of Chromosome 21.Mosaic is similar to Trisomy 21 in that it still has the extra chromosome in the cell, but also some of the other cells in the body have a normal amount of chromosomes.
Difference between the chromosomes of a person with Down syndrome and a person without Down syndrome?
An individual with Down Syndrome has the presence of all or part of an extra 21st chromosome.
People with down syndrome have how many chromosomes?
47There are 47 chromosomes in someone with Down syndrome; the 21st pair has an extra chromosome. Most people have 46 chromosomes. Down syndrome is also known as "Trisomy 21" - a reference to the fact that someone with Down syndrome has 3 pairs of chromosomes on their 21st pair.
What is a chromosomal disorder that could result from nondisjunction?
Disorders, such as Down's Syndrome, are caused by nondisjunction.
