A person with the Y chromosome is considered to have the "boy chromosome". This chromosome is responsible for determining male sex characteristics. Males typically have one X chromosome and one Y chromosome (XY), while females have two X chromosomes (XX).
The Y chromosome contains a gene called the SRY gene, which triggers the development of male characteristics during fetal development. While the Y chromosome is essential for male development, other genes on the X chromosome also play a role in male sex determination and development.
