    The answer is: from mother

    In a human diploid somatic cell (2n), there are in total 46 chromosomes - 22 autosomal chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes. In males, there is one X and one Y chromosome (XY) while in females, there are two XX chromosomes (XY).

    During the formation of gametes, a female could give only X chromosomes, so gametes from the mother contain one X chromosome. But, a male could give X or Y chromosome, so gametes from the father contain either X or Y chromosome.

    Female gamete and male gamete fuse to form a zygote. Male zygote must contain both X and Y chromosome. It inherits Y chromosome only from the father, so X chromosome must be inherited from the mother.
