Sex chromosomes are a pair of chromosomes that carry the genes determining the sex of an individual. In humans, females have two X chromosomes, while males have one X and one Y chromosome. The presence of the Y chromosome is crucial for male development. Every individual must have at least one X chromosome, and the combination of X and Y chromosomes determines the sex of an individual. The X chromosome is inherited from the father, ensuring that both sexes always have one functional copy of the X chromosome. Sex chromosomes play a significant role in sex determination and influence sexually dimorphic development, including brain gender
