The XY chromosome is one of the two types of sex chromosomes found in humans and many other species. It is responsible for determining the biological sex of an individual, particularly in males.
In humans, males typically have one X chromosome and one Y chromosome, while females have two X chromosomes. The presence of the Y chromosome in males determines the development of male reproductive organs and other masculine traits.
The Y chromosome carries genes that are crucial for male sexual development, including the SRY gene (sex-determining region Y). The SRY gene triggers the development of testes, which produce testosterone and other hormones responsible for the development of male characteristics during embryonic development.
In summary, the XY chromosome refers to the combination of sex chromosomes found in males, where the presence of the Y chromosome determines male sexual development.

Sex chromosomes usually determine whether you are female or male. Women are XX. Men are XY. However, genetically, a few women are actually men.
