Neither you nor your partner has to have a genetic disorder in order to pass one on to your children. Prenatal genetic testing refers to a number of blood tests that two prospective parents can take before getting pregnant to determine whether their children are likely to inherit a harmful genetic disorder.
Genetic testing may be recommended for parents who have a family history of genetic disorders, or who belong to certain ethnic backgrounds. If neither parent or only one parent, is a carrier of the gene, the disorder will not be passed on to the children. If both parents are carriers, however, then their children have a 25% chance of inheriting the disorder. Learn more about genetic testing by clicking the links below.
