X contains the coding for such things as female estrogen (and other hormones) production, construction of the vagina and female breasts, muscular structure, female fat allocation, and, in some scientists beliefs (it's not proven, and it might not be. This is one complex chromosome, in a species with a large enough amount of complexity to begin with), the coding for attraction to males.
Y contains the coding for such things as male hormone production, construction of the penis and testicals, muscular structure, fat allocation, and, perhaps, attraction to females.
Basically, any differences between male and female are coded on X and Y. Y's job is to overpower X in a man, though it sometimes fails to do so, producing females with XY chromosome sets.
