Fig. 4. bam is epistatic to Mad. Confocal projections of tumorous
ovarioles from young (under 5-day-old) females of genotype
P{hs-FLP};P{arm-lacZ}
P{ry+,hs-neo,FRT}40A/Mad12
P{ry+,hs-neo,FRT}40A; bamD86 (anti-Hts,
green; anti-lacZ, red). (A) Non heat-shocked control. (B) After
heat-shock-induced mitotic recombination, doubly mutant germ cells, which do
not express lacZ, had rounded spectrosomes, indicative of failure to
form cyst cells. Arrow indicates terminal filament.
