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.

Type of mutation that causes Trisomy 18?

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.

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.
