What is the Difference Between Male and Female Karyotypes?

The main difference between male and female karyotypes lies in the 23rd pair of chromosomes, which are called allosomes and determine the sex of an individual. Here are the key differences between male and female karyotypes:

• Male Karyotype: Each cell nucleus contains 46 chromosomes (23 pairs), with the 23rd pair consisting of an X and a Y chromosome (XY). This karyotype is used to identify male sex chromosome abnormalities, such as Klinefelter syndrome.
• Female Karyotype: Each cell nucleus also contains 46 chromosomes (23 pairs), but the 23rd pair consists of two X chromosomes (XX). This karyotype is used to diagnose female sex chromosome abnormalities, such as triple X syndrome and Turner syndrome.

Karyotypes can be used for various purposes, including prenatal diagnostics, tumor studies, and understanding cellular function, taxonomic relationships, and past evolutionary events.

Comparative Table: Male vs Female Karyotypes

The main difference between male and female karyotypes lies in the 23rd pair of chromosomes. Here is a table summarizing the differences:

Male karyotypes have one X and one Y chromosome in the 23rd pair, while female karyotypes have two X chromosomes in the 23rd pair. Autosomes, which are present in both males and females, are the same in number and structure. Karyotypes are used to determine sex chromosome abnormalities, such as Klinefelter syndrome in males and Turner's syndrome in females.
