dltA1 mutant eye discs are very small and lack the antennal part. dltA1 mutant eyes, generated using the Minute technique, can be significantly smaller than wild-type eyes, although this phenotype is extremely variable. BrdU incorporation is still able to occur during eye development, indicating that DNA synthesis during proliferation is not affected.
