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.

∙ 8y agoThere 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.

How can an individual get Down Syndrome?
One does NOT GET Down's syndrome, a person is born with it. Down's syndrome occurs in the early stages of development, more commonly in older mothers. It is when there is an extra chromosome in trisomy 21. This extra chromosome is caused by a nondisjunction which is when there is a failure of one synaptic pair of chromosomes to separate during anaphase 1.
