Mesodermal expression of eve is normal in null eve mutants carrying eveΔRP2C. However, the odd-numbered parasegments are narrower than normal, indicating a lower activity at the blastoderm stage. Only one out of five lines tested allowed rescue to adulthood.
eve null mutants carrying a copy of eveΔRP2A and eveΔRP2C in trans show normal mesodermal expression of eve and normal segmentation and are efficiently rescued to adulthood.
