Under normal circumstances, women’s blood does not usually contain Y chromosomes. The human body has a total of 23 pairs of chromosomes, of which 22 pairs are autosomes and 1 pair is a sex chromosome, or what we call the X chromosome and the Y chromosome, which are used to differentiate males from females. Those with X chromosome are usually female and those with Y chromosome are usually male. However, there are also abnormal chromosomes such as XXY and XYY in clinical practice, most of which are related to genetic mutations. Most of them are related to genetic mutations, and some of them are related to excessive exposure to radiation. From the point of view of secondary sexual characteristics, males have female characteristics and females have male characteristics. If you have female chromosome abnormality, you should go to the regular hospital in time for genetic examination and counseling to avoid adverse consequences.
