If heredity plays the key role in determining whether a child is born with a cleft, does that mean that I will have other children (or grandchildren) with clefts?
Not necessarily. Even geneticists, whose science it is to make predictions about heredity, cannot predict with 100 percent accuracy whether or not a given pair of parents will have a baby with cleft palate. But geneticists can help to figure out what the chances are, given your particular family history.
