Trisomy 21 is down's syndrome, which is an extra copy of chromosome 21
Another name for trisomy-21, commonly known as Down syndrome, is trisomy 21.
Well, honey, Down syndrome is caused by an extra copy of chromosome 21, also known as trisomy 21. It's like having a bonus chromosome that messes with the genetic party. So, to put it simply, trisomy 21 is the culprit behind Down syndrome.
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.

Trisomy means having three copies of a chromosomes. Turner's syndrome is NOT an example of trisomy. Someone with Turner's syndrome has only one X chromosome. Down's syndrome IS an example of trisomy. Someone with Down's syndrome has 3 copies of chromosome 21. Klinefelter's syndrome is a tricky one. On one hand, it would be considered trisomy because they have 3 sex chromosomes. However, they are not all the SAME sex chromosomes. Someone with Klinefelter's has 2 X chromosomes and one Y chromosome.
Down syndrome is also known as Trisomy 21.
Well Down Syndrome is sometimes called Up Syndrome because most kids with Down Syndrome are very happy.Trisomy 21
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.
