Baldness is passed from mothers to sons. Obviously the mother is a carrier (no obvious symptoms). If your mother's father was bald, you have the baldness gene.

An X-linked, or sex-linked, disorder affects only males and is passed from mother to son. Examples of X-linked disorders are some types of Fragile X syndrome (a form of mental retardation), Duchenne muscular dystrophy, and hemophilia. There are rare types of hemophilia that occur in females, but 95% of hemophiliacs have the X-linked variety.

I know there are many, this is one that I know of.
Hemophilia is an inherited disease, meaning that a gene responsible for causing hemophilia is passed from parent to offspring. In the United States, about one or two in every 10,000 male infants is born with it. Approximately 80 percent have hemophilia A, and 20 percent have hemophilia B. Hemophilia affects mostly males. The chances of having a child with hemophilia are the same for all racial and socioeconomic groups. Although females rarely have hemophilia, they may carry the gene that causes hemophilia and pass it on to their children

The two most common are red- green color blindness and hemophilia.
