A human cell nucleus contains 46 chromosomes, arranged in 23 pairs. The 23rd pair, known as allosomes, determines the sex of an individual. In males, this pair is represented by X and Y chromosomes. A karyotype is a visual representation of all the chromosomes in a cell nucleus, revealing their size, number, shape, and type. This is often depicted in a diagram called a karyogram.
Karyotyping is often used in medical diagnostics, particularly for identifying sex-linked diseases that are passed through the X or Y chromosomes.

In females, the allosomes consist of two X chromosomes. The female karyotype provides a comprehensive view of a woman’s chromosomes and can be used to identify any potential chromosomal abnormalities. A well-known chromosomal abnormality in females is Turner’s syndrome, which is caused by the absence or abnormality of an X chromosome.
