Abstract
Organism symmetry via body plan is the balanced arrangement of structural features (internally or externally) that is definable in terms of dimension (2D or 3D) and geometry (contours, surfaces, boundaries). Symmetry is evident at the endpoint of morphogenesis and at each scale, from genes to cells to organism to population or higher taxonomic level. Symmetry may change from juvenile
