Figure 7. Progeny row showing uniformity of F3 family to which the plant shown in figure 6 belonged. with lower means than will large individuals. As there are many indi- cations that the plants entering into this cross were very nearly true homozygotes I have endeavored to test this proposition. Of course, as might be expected by pro-Mendelians, in such a cross the variability of the F1 population is so low that the extremes selected differed by only 8 mm. Nevertheless five F2 frequency distributions from different F1 parents are presented in table 3. The statistical constants shown in table 4 emphasize the fact that the means and the standard deviations Genetics 1: Jy 1916.
