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.
