Detailed Description
Statement
Reference

Flies carrying CycEI.hs.2sev have a rough eye phenotype. Ommatidia containing more than the normal complement of photoreceptor cells are frequently seen, although ommatidia with fewer photoreceptor cells than normal as well as other pattern irregularities are also seen. An additional band of BrdU incorporation is seen in the posterior region of the eye-antennal disc in larvae carrying CycEI.hs.2sev.
