Figure 3
The distribution of phenotypic gender in tetraploid and hexaploid hermaphrodites of M. annua growing under three levels of nutrient addition (0, 0.3 and 0.9 g L−1). The standardized phenotypic femaleness (PG) is graphed against its individual rank. N = 60 for all curves, except for tetraploids growing at 0.3 g L−1 where N = 59. Plants with a PG value of 0 and 1 are strictly male and female, respectively. See text for further details.
