The lesion in the DRN induced changes in the proportions of stages of the cycle of seminiferous epithelium at 45 or 65 days-of age. Mosaic plot for stages of the cycle of seminiferous epithelium, treatment, and age at sacrifice. In the mosaic plot each cell of a contingency table is represented by a rectangle whose area shows the cell frequency or deviation from independence (Friendly, 1994). The area of each cell is proportional to cell frequency. Cells with positive, negative, or no deviation from independence are filled with blue, red, or gray color, respectively (Please see the look up table at right side of the mosaic)
