Fig. 2. hnt^peb is a viable allele that causes eye roughening. Scanning electron micrographs of adult eyes. (A) Wild-type eye. Note the regular arrangement of facets. (B) Eye from a hnt^peb/hnt^peb fly raised at the restrictive temperature. Note the disorganized facets, causing roughening. (C) Eye from a hnt^peb/hnt^XE81 fly. Note the similar phenotype to that shown in B. This failure to complement hnt^peb was observed for three other alleles of hnt (hnt^EH704a, hnt^XO01 and hnt¹¹⁴²; data not shown). In all cases, anterior is towards the left and dorsal is towards the top of the page.
