1. Cystic Fibrosis. Cystic Fibrosis is one of the most widespread inherited genetic disorders. It prominently affects Caucasians who are Ashkenazi Jews. It occurs only when both parents are carriers, which gives their children a 1 in 4 risk of contracting the disease.

Although it is much rarer, a girl can have hemophilia, but she would have to have the defective gene on both of her X chromosomes or have one hemophilia gene plus a lost or defective copy of the second X chromosome that should be carrying the normal genes.
