What is trisomy mutation?
A trisomy is when a person has 3 versions of a chromosome. 'Normal' humans will only have 2 of each chromosome. For example, having 3 versions of chromosome 21 is known as Trisomy 21 or Down Syndrome.
Down syndrome involves trisomy?
Yes, Down syndrome is typically caused by trisomy 21, which means there is an extra copy of chromosome 21. This condition can lead to developmental delays, intellectual disability, and certain physical characteristics.
What are the major chromosomal changes in trisomy?
Trisomy is defined as the presence of three homologous chromosomes. For example, Down's Syndrome is caused by trisomy-21, 3 copies of chromosome 21.
What is the presence of three of a particular chromosome?
The presence of three copies of a particular chromosome is known as trisomy. This genetic condition can lead to developmental abnormalities, such as Down syndrome which is caused by trisomy of chromosome 21.
Is down syndrome caused by a virus or a bacteria?
NO, it is caused by the Trisomy of the human chromosome 21
Down syndrome is caused by having an extra copy of what chromosomes?
21, the condition is also referred to as trisomy 21.
What is the condition in which an individual has three copies of a chromosome?
The condition in which an individual has three copies of a chromosome is called trisomy. It can result in genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21.

What trisomy causes Down syndrome?
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.
Is down syndrome caused by a virus or a bacteria?
NO, it is caused by the Trisomy of the human chromosome 21
What is the disorder caused by having an abnormality on chromosome 21?
Down's Syndrome or trisomy 21.
What is monosomy 21?
Monosomy 21 refers to a genetic condition where an individual is missing one copy of chromosome 21, resulting in a total of only one chromosome instead of the normal pair. This condition is extremely rare and is often associated with severe developmental and physical challenges. Unlike Down syndrome, which is caused by an extra copy of chromosome 21 (trisomy 21), monosomy 21 typically leads to more severe clinical outcomes and is usually not compatible with life.
Trisomy is a mutation that results in a cell having an extra?
A trisomy is a condition in which a person has three copies of a chromosome instead of the usual two copies. A person can have full trisomy (three copies in every cell) or mosaic trisomy (three copies in some cells but not all).
Down syndromeis caused by errors in what?
Downs syndrome is caused by a genetic mutation called trisomy. Trisomy is when an extra chromosome is present on one set of chromosomes, so instead of the 46 chromosomes of a normal human there are 47. Trisomy can often result in miscarriage as the body cannot cope well with extra chromosomes. Downs syndrome is when there is an extra chromosome 21. Other genetic defects which are caused by trisomy are Edwards syndrome and Patau syndrome.
