Individuals with XO chromosomes have Turner syndrome. This chromosomal condition occurs in females when one of their two X chromosomes is either missing or partially missing.
Key points about Turner syndrome:
- Affects only females: It is a condition that only affects females.
- Missing or partially missing X chromosome: The defining characteristic of Turner syndrome is the presence of only one X chromosome or a partially missing X chromosome.
- Various symptoms: The severity of the symptoms can vary significantly, ranging from mild to severe. Some common symptoms include short stature, heart defects, and infertility.
Examples:
- A female with Turner syndrome may have only one X chromosome in all of her cells (45,XO).
- In some cases, a female may have a mosaic pattern, meaning that some cells have two X chromosomes (XX) while others have only one (XO).
