What family members show signs of x-linked dominant disorder?

Depends on sex: Any males with the gene will have the disorder assuming the gene is expressed. So will a female. A female with the disease and one x with the gene has a fifty fifty chance of passing it on to her children. If both of her xs have the gene, all children will get the gene. A male with the gene has a fifty fifty chance of passing it on to his daughters but cannot pass it on to his sons.
