Mutation of the four clustered polyuridine tracts.
msl-1γ269, msl-1MPU, msl-2Hsp83.PK has visible | female phenotype
msl-1MPU, msl-2Hsp83.PK has visible | female phenotype
msl-1γ269, msl-1MPU, msl-2Hsp83.PK has wing phenotype
msl-1MPU, msl-2Hsp83.PK has wing phenotype
Females carrying msl-2Hsp83.PK which survive to adulthood show a delay in eclosion. This developmental delay is further increased if the females are also carrying msl-1MPU. msl-1γ269/+ females carrying msl-2Hsp83.PK and msl-1MPU often have a scalloped wing phenotype.
Rescues the recessive lethality of msl-1γ269 males.
