Heterosis of F1 hybrids of wild S. cerevisiae, and correlation between heterosis and the genetic distance of parental strains at 40°C. (A) Maximum growth rate (MGR) and growth efficiency (GE) of F1 hybrids relative to the average values of their parents (mid-parent value [MPV]). (B) Proportions of F1 hybrids showing mid-parent heterosis (MPH), better-parent heterosis (BPH), and outbreeding depression. (C) Correlation between genetic distances of parental strains and growth performance of F1 hybrids relative to the MPV (MPH) or the better parent value (BPH) in terms of MGR or GE.
