which parent is fragile x syndrome inherited from
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.
