This concept has been applied to the analysis of the size and shape of gourd fruits,^ where it is found that a genetic analysis on the basis of linear dimensions leads to confused results, whereas an analysis on the basis of ratios between length and breadth permits of a simple interpretation of the results in terms of a few clearly defined **shape-genes" (figs. 199, 200). ^ Sinnott and Hammond, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Huxley, Julian, 1887-1975; De Beer, Gavin, Sir, 1899-1972.
