It's the starting pt: Parent study comes first.A person can appear normal if they carry all the proper chromosome material but with part belonging to one chromosome swapped with another.(ie, part of a #15 is on #21) When fertilization occurs, the fetus may get part of the mistake and not the other & be defective.Some of these have a partial chance of normal birth, some would always end up a defect.See a geneticist.
