Figure 6. Epistatic interactions may account for the systolic diameter phenotype.

Figure 6

RIL 64, 85 and 187 (see Table S3) each have an extreme narrow diameter similar to the parent WE70 line, whereas RIL 147, 148 and 144 (indicated by bold) have wildtype-like diameters. Each was crossed to either the second (WE70-2, light gray) or third (WE70-3, dark gray) chromosome WE70 substitution lines. Progeny from all the crosses show intermediate to wildtype heart diameters. Significant pair-wise comparisons are indicated (*p<0.05, **p<0.01, ***p<0.001). All other comparisons relative to yw (white bar) were not significant. WE70 parental line, black bar on the right, is also shown for comparison. 12–30 flies of each line were analyzed.
