The cells of triploid animals, like certain salamanders, are individually larger, yet their overall body size is no different from that of diploids. Pose a developmental hypothesis for the control of morphogenesis in such animals

The increase in cell size with no concomitant increase in body size means that the triploids produce fewer cells for the same body size. Intercellular signals are important in morphogenesis, so perhaps size and shape of tissues and organs is sensed and communicated by chemical signals generated, say, when certain cell types come in contact. A certain size or dimension would be reached sooner with larger cells, triggering the next set of developmental genes and preserving overall body dimensions.
