Sequences encoding the cytoplasmic tail of mew that were present in mewUAS.cMBa have been replaced with sequences encoding the cytoplasmic tail of if.
if::mewUAS.cMBb, Scer\GAL4twi.PG, Scer\GAL4how-24B is a suppressor of lethal | recessive | embryonic stage phenotype of ifB4
if::mewUAS.cMBb/Scer\GAL448Y is a suppressor of lethal phenotype of mewM6
if::mewUAS.cMBb/Scer\GAL448Y is a suppressor of phenotype of mewM6
The embryonic lethality of ifB4 homozygotes is rescued in approximately 1/3 of cases by if::mewScer\UAS.cMBb expressed using Scer\GAL4how-24B in conjunction with Scer\GAL4twi.PG.
