photoreceptor cell R7
ttkbose1/ttkbose45 flies have extra R7 photoreceptor cells in some ommatidia.
ttk[+]/ttkbose45 is an enhancer of phenotype of aoppok-15
ttk[+]/ttkbose45 is an enhancer of photoreceptor cell R7 | ectopic phenotype of aoppok-15
aoppok-1, ttk[+]/ttkbose45 has eye phenotype
Heterozygosity for ttkbose45 reduces the size of the compound eye in the aoppok-1 homozygous background.
