wORF.ab3'UTR flies (in a w[-] background) display a relatively light eye colour.
wORF.ab3'UTR has abnormal eye color phenotype, suppressible by lncRNA:let7CKO1
wORF.ab3'UTR flies (in a w[-] background) whose eyes are composed exclusively of let-7-CKO1 mutant cells display a darker eye colour compared to wORF.ab3'UTR alone.
