From: Extensive heterosis in growth of yeast hybrids is explained by a combination of genetic models
Growth analysis of reciprocal backcross populations. The mean Log2 DT (y axis) of the hybrid, diploid parental strains and reciprocal backcross populations (x axis) at different temperatures. The horizontal lines are drawn at the level of the best parent (BP) in each condition. The values of the backcrosses (BC1) are means of about 180 diploid strains per population. Asterisk above a BC1 bar denotes that the mean of the BC1 population was significantly different (P<0.05) from the value of the hybrid and the respective backcross parent. Denoted by curly brackets and small letters y and x is an example of the differences in growth rates, the ratio of which was tested to support or disprove the dominance complementation model. The analyses were carried out in two genetic backgrounds in which the hybrid was heterotic. The background of (a) 7 × 37 and (b) of 38 × 37.
