What is a sex chromosome?

Sex chromosome is a chain structure in the nucleus of the cell that determines the sex of the body. In humans, each cell usually has one pair of sex chromosomes marked with letters x and Y. The presence of chromosome y distinguishes a male from female properties. Most people have only one pair of these chromosomes in each cell, but some individuals have more or less, resulting in a certain genetic disorder. In the human body, the core of each cell contains 22 chromosomes called autosomes and one pair of sex chromosomes. One humanosome of the human sex is marked either X or Y and these chromosomes are paired as XX or XY. Marking XX means that a person will have female properties, while a couple XY suggests that an individual will carry male properties. The specific biology of these chromosomes and the way I connect me is to have two XS pairing, but not two YS. All other cells that contain two X chromosomes will be deactivated. During the concept when an egg cell containing two x chromosomesIt is a sperm cell that contains one x and one chromosome, a random pair is made, including two X or a combination of XY.

sexual chromosome not only determines human reproductive organs, but is also responsible for other qualities that are usually associated with men or women. For example, a person who carries the xy sexual chromosome generally develops strong facial hair, prominent Adam's apple and a relatively deep voice. Otherwise, individuals who have XX chromosome usually develop distinctive female characteristics such as the mammary glands, enlarged breasts and finer, thinner facial hair.

There are situations where a person has an abnormal pair of sex chromosomes. For example, sometimes an extra X is sometimes joined to the pair, or sometimes there is only one chromosome rather than two. In these cases, the person is likely to develop certain disorders such as Turner's syndrome.

in other casesCh chromosome X may bear abnormality, which manifests itself as a particular disease, such as haemophilia or spiritual muscle dystrophy. These types of conditions are considered recessive in that they are almost always exclusive to men. This is because both X chromosomes would have to be defective for a woman who would show symptoms. On the other hand, because one has only one X chromosome, if it is defective, it will probably prove symptoms of the disorder.
