Where do males typically receive their X-chromosome?

Explanation:
Males typically receive their X-chromosome from their mother because the inheritance of sex chromosomes follows specific patterns. In humans, males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). Since males inherit their Y chromosome from their father, the X chromosome must come from their mother. This is a fundamental aspect of human genetics and sex determination; it highlights the maternal contribution to the X chromosome in males. The father contributes the Y chromosome, which determines the male sex. Thus, males get their X chromosome solely from their mother.
