Here's why:
* Diploid: A normal human cell has 46 chromosomes (23 pairs), this is called a diploid cell.
* Aneuploidy: Any deviation from this 46-chromosome number is considered aneuploidy.
* Monosomy: One chromosome is missing (e.g., Turner syndrome, where a female has only one X chromosome).
* Trisomy: An extra copy of a chromosome is present (e.g., Down syndrome, where there are three copies of chromosome 21).
It's important to note that aneuploidy can have significant consequences for human health, often leading to developmental problems or genetic disorders.
