A trisomy is a chromosomal condition characterized by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.
Trisomy means the presence of an extra chromosome in some or all of the body's cells. This results in a total of three copies of that chromosome instead of the normal two copies. For example, Down syndrome (trisomy 21) is caused by having three copies of chromosome 21 instead of the usual two copies.
This genetic condition is the result of a genetic mutation where your cells don't divide as they should. You can't prevent this abnormality from happening during cell division.
