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.

These are called fatal genetic mutations. Same examples are: Tay-Sachs disease, Neimann-Pick disease, Trisomy 18 and Trisomy 13 are "Edwards Syndrome" and "Patau Syndrome," respectively and Cystic fibrosis
Trisomy 13, also known as Patau syndrome, is a chromosomal mutation where there is an extra copy of chromosome 13 in each cell. This condition can lead to various physical and intellectual disabilities.
Trisomy-21, also known as Down syndrome, results from an extra copy of chromosome 21. Instead of the usual two copies, individuals with Down syndrome have three copies of chromosome 21. This extra genetic material can lead to various physical and cognitive differences.

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).
These are called fatal genetic mutations. Same examples are: Tay-Sachs disease, Neimann-Pick disease, Trisomy 18 and Trisomy 13 are "Edwards Syndrome" and "Patau Syndrome," respectively and Cystic fibrosis
Trisomy 18 is caused by a type of mutation called nondisjunction, where an error in cell division results in an extra copy of chromosome 18. This leads to the presence of three copies of chromosome 18 in each cell instead of the normal two copies.
Trisomy 13, also known as Patau syndrome, is a chromosomal mutation where there is an extra copy of chromosome 13 in each cell. This condition can lead to various physical and intellectual disabilities.

Trisomy-21, also known as Down syndrome, results from an extra copy of chromosome 21. Instead of the usual two copies, individuals with Down syndrome have three copies of chromosome 21. This extra genetic material can lead to various physical and cognitive differences.
Trisomy an abnormality in chromosomal development.
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.
