Only if that gene happens to be on the sex chromosomes! There are 22 other chromosomes, though. I'm no biologist, but I believe you are referring to sex-linked traits. Hemophilia is the most studied example, but there are many (http://en.wikipedia.org/wiki/Sex_linkage#X-linked_recessive_inheritance http://en.wikipedia.org/wiki/Sex_linkage#X-linked_recessive_...). In these disorders, males with the gene will always get the disease, where as women can act as "carriers", carrying the trait for the gene on one of their X chromosomes, but not experiencing any of the symptoms of the disorder. Unfortunately for your theory, this interesting phenomenon has little to do with other genes. There is no magic link between separate chromosomes, and almost all of our important traits lie on the 22 other chromosomes, which do not experience this sex-linkage.
