Many edslH8/edK1102 ommatidia over- or under-rotate; the variance (s.d.) in degree of rotation is greater than in wild type in adult eyes. The mutant s.d. does not become statistically distinct from wild type until row 7 in the third larval instar eye disc, approximately 2-3 rows after the initiation of rotation (the time at which the anterior and posterior cone cells join the ommatidial precursor). The s.d. is still significantly greater in the mutants than in wild type at row 15, when rotation is complete in wild type.
edK1102/edslH8 has ommatidium phenotype, enhanceable by fred[+]/fredH24
