Females have genotype XX; males have genotype XY. Although it is the male's genetic contribution that determines the sex of the baby, that's not the whole story.

Popular fiction depicts sperm as a bunch of wild and crazy guys that want to fertilize the egg, which they do forcibly. However, recent microphotographs demonstrate that the eggs puts out a psuedopod that binds to the cell membrane of the selected spermatozoan and reels that bad boy in, much against his will. In that sense, one can blame the egg, and since the mother makes the eggs, the mother can be blamed for the sex of the child.

Males are XY, and sperm can contain either sex chromosome.
Females are XX, so eggs always have the X chromosome.
