Intermediate eye pigment levels are observed in glu88-82, barrL305 double mutants with a In(1)wm4h background, showing that glu88-82 suppressor effects of PEV are not dominant over the enhancer activity of barrL305.
Chromatin condenses nonuniformly in prophase and prometaphase in postblastoderm Cap-GK1 barrL305 double mutant embryos. By metaphase, chromosome condensation has reached wild-type levels. Chromatid separation defects are seen in anaphase when only the fourth chromosome is clearly seen to separate, and lagging chromosomes are seen in telophase. The double mutant postblastoderm embryos have an increased number of prometaphase figures compared to wild-type embryos, suggesting that the length of prometaphase may be increased in the mutant embryos.
