I think it has to do with men only having one copy of the X chromosome. For example women are rarely color-blind because the genetic defect is a recessive and it is on the X-chromosome therefor a woman has to have two bad copies to be colorblind. Different cells in the body have one of the two X-chromosomes inactivated so that females are affectively a mosaic of the traits carried by the X chromosome.
Patterns of X Inactivation.
X inactivation is normally random in female somatic cells and leads to mosaicism for two cell populations expressing alleles from one or the other X (Fig. 6-13). Where examined, most females have approximately equal proportions of cells expressing alleles from the maternal or paternal X (i.e., approximately 50:50), and approximately 90% of phenotypically normal females fall within a distribution that extends from approximately 25:25 to approximately 75:25 (seeFig. 6-13). Such a distribution presumably reflects the expected range of outcomes for a random event (i.e., the choice of which X will be the inactive X) involving a relatively small number of cells during early embryogenesis. For individuals who are carriers for X-linked single-gene disorders (seeChapter 7), this X inactivation ratio can influence the clinical phenotype, depending on what proportion of cells in relevant tissues or cell types express the deleterious allele on the active X chromosome.

Nope. Think again. The scientific reason is not the answer.
