Indirect flight muscles accumulate little or no MHC, have no thick filaments, and show no organized myofibrils. The four smaller cells of the TDT display reduction in thick filament number and myofibril size; large TDT cells unaffected. homozygous viable

41% of wupAhdp-3/Y ; Mhc12/Mhc12 flies have an upheld wing phenotype and 59% hold their wings normally. 41% of wupAhdp-3/Y ; Mhc12/Mhc2D flies have an upheld wing phenotype and 59% hold their wings normally. 61% of wupAhdp-3/Y ; Mhc12/MhcD45 flies have an upheld wing phenotype and 39% hold their wings normally. The indirect flight muscles of wupAhdp-3/Y ; Mhc12/Mhc2B and wupAhdp-3/Y ; Mhc12/Mhc2F flies show a partial hypercontraction phenotype.
