Während man sagen kann, dass beim Menschen durchschnittlich eine Zwillingsgeburt auf etwa 89 einfache Geburten vorkommt tritt eine Drillingsgeburt auf (89)2 einfache Geburten auf, eine Vierlingsgeburt auf (89)3; überhaupt, soweit dies in Grenzen der Möglichkeit liegt, erscheint eine x fache Geburt auf (89)x–1 einfache Geburten.
