Fig. 4: Relationship between levels of inbreeding depression and opportunities for selection (CV²) for outcrossed and inbred offspring.

Fig. 4

Panels show how ID was related to CV² measured within treatment cells (stress × competition) in either (a) outcrossed or (b) inbred progeny. Lines show linear regressions within groups with and without competition (N = 6 each). Note that competition with a grass (filled symbols) significantly increased CV² in outcrossed (p = 0.014) and selfed offspring (p = 0.004) but had inconsistent effects on ID. The shaded gray area in (a) shows four treatments that increased both CV² and ID relative to the control, supporting the phenotypic variability hypothesis, in contrast to the seven others that did not.
