|---|---|---|---|---|
| Muscle affected | ths759/CyO | ths759/CyO × Df/CyO | pyr18/CyO | pyr18/CyO × Df/CyO |
| VO | 7.8 (28) | 15 (26) | 16 (19) | 21.4 (42) |
| SBM (duplication) | 34.8 (23) | 24 (25) | 29.6 (37) | 3.6 (28) |
| SBM (absence) | 0 (23) | 16 (25) | 22.2 (37) | 14.3 (28) |
Quantification of muscle defects in stage 16/17 embryos stained with antibodies to Mhc (as depicted in Fig. 6). Because selection of homozygous embryos using a marked balancer was not possible at this stage, muscle defects were scored in all embryos from a heterozygous cross as indicated. n, number of embryos analysed. Df, Df(2R)ED2238; VO, ventral oblique muscles 4-6; SBM, segmental border muscle.
