Levels of reactive oxygen species (ROS) within cells of F1 hybrids of wild S. cerevisiae and their parents growing at 40°C. (A) Cellular ROS levels of F1 hybrids and average cellular ROS levels of their parents (MPV) in the groups of heterotic and depressed F1 hybrids, respectively. (**) P < 0.01 (Mann–Whitney U test). (B) Cellular ROS levels of heterotic and depressed F1 hybrids relative to the MPV. The relative ROS level in a F1 hybrid was calculated according to the formula log2 (F1/MPV).
