No, it's not just males who have the Y chromosome; it's a common misconception. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of the Y chromosome in males is what typically determines male sex characteristics. However, in very rare genetic conditions, variations might occur, but this is the general rule.
