In genetics, what is a trisomy?
In genetics, a trisomy is having 3 chromosomes instead of the usual pair of chromosomes. For example, trisomy 21 is down syndrome, where the 21st chromosomes are not pairs, but triples.

Trisomy is a genetic disorder characterized by the presence of an additional chromosome in a cell, resulting in three copies of a particular chromosome instead of the usual two. This condition can lead to developmental abnormalities and health issues, depending on which chromosome is affected. One well-known example is Down syndrome, which is caused by trisomy of chromosome 21.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- If an autosome is present in only one copy at conception, that individual will not develop to term. Yet human males have only one copy of the X chromosome and they do develop normally. Why is there a difference?
- Why does each cell have 2 copies of each gene is it because when cell dived the copy the nucleus and the genes present in the nucleus?
