Why are genetic diseases carried by genes on the X chromosome more common in male offspring than female offspring?

Because in males they have only 1 X chromosome. The other one is Y. But in females they have 2 XX chromosomes so the chance that X chromosome will carry disease to cause illness is lower. Example: lets say xx (recesssive) phenotype makes illness, whereas XX (dominant) is healthy. A woman can have XX, Xx, xx right? Since Xx is a carrier and XX is healthy you wont see the illness. only xx can make illness. 1/3 chances she is sick. However in males they have XY. so he can only have either XY or xY. No carrier form is present. The chances he will be sick is %50. got it? Im a genetic engineer and molecular biolog so count on me :)
