Trisomy is when three copies of a chromosome are present instead of two (all chromosomes normally come in pairs) while most parents-to-be are familiar with down syndrome and will undergo prenatal screening to detect it, there are other, potentially more serious trisomies that may occur, including edwards syndrome, patau syndrome, and otherssome may cause few, if any, symptoms, while others.
