    sex chromosome determining male biological characteristics in humans

    The Y chromosome is one of the two sex chromosomes in humans, the other being the X chromosome. It is typically found in males and carries genes that are crucial for the development of male reproductive tissues and secondary sexual characteristics. The presence of a Y chromosome generally determines male biological sex, as it contains the SRY gene, which triggers male development.
