Grouped into 23 pairs, we get one set from our mother and the other from our father. One of these pairs of chromosomes determines if a person is male or female: Males (XY) get the X chromosome from the mother and the Y chromosome from the father. Females (XX) inherit one X chromosome from each parent. The Fragile X premutation can be passed silently down through generations in a family before a child is affected by the syndrome.
Families with an X-linked dominant disorder often have both affected males and affected females in each generation. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons (no male-to-male transmission).-linked dominant. X-linked dominant disorders are caused by mutations in genes on the X chromosome. Females are more frequently affected than males, and the chance of passing on an X-linked dominant disorder differs between men (illustration) and women (illustration).
