Generalized linear models using normal distribution and identity link of within-population fixation index (Fis: a–c) and population size (d–f) according to petal index (Petal W/L: a), within-population fixation index (Fis: d), pollen-to-ovule ratio (P/O ratio: b, e), and seed weight (µg: c, f) for all populations of Moehringia tommasinii. * p < 0.05, ** p < 0.01, *** p < 0.0001
