In humans, the X chromosomes are much larger than the Y chromosome and contains thousands of more genes than the Y chromosome. Therefore, many traits are carried only on the X chromosome.

Sexual dimorphism
Sexual dimorphism is a phenotypic differentiation between males and females of the same species. This differentiation happens in organisms who reproduce through sexual reproduction, with the prototypical example being for differences in characteristics of reproductive organs. Other possible examples are for secondary sex characteristics, body size, physical strength and morphology, ornamentation, behavior and other bodily traits. Traits such as ornamentation and breeding behavior found in only one sex imply that sexual selection over an extended period of time leads to sexual dimorphism.
