The size of the L2 dendritic tree in per⁰¹ arrhythmic mutant in DD.

Flies of 21D-GAL4×UAS-mCD8-GFP in per⁰¹ background D. melanogaster line were held in constant darkness (DD) and sacrificed at CT1 – 1 h from the beginning of subjective day, CT4 – 4 h from the beginning of the subjective day, CT13 – 1 h from the beginning of subjective night, CT16 – 4 h from the beginning of subjective night. There was not significant differences in the size of L2 dendritic tree during the subjective day and subjective night in males and in females.
