      fruC1/fruF males show significantly reduced copulation success compared to controls in single-pair courtship assay.

      fruC1/fruF males show courtship song defects: sine song is almost completely absent, the interpulse interval of the pulse song is longer and more varied than normal, the carrier frequency of pulse song is highly variable and in the dark, pulse song is dramatically reduced.

      fruC1/fruF males show a significant decrease in the number of vPR6 and aDT2/mAL neuronal cells per hemisphere compared to fru[+] males, but no significant change in the number of pMP4/P1, pIP10, dPR1, vPR1, aSP1 or aSP2 neuronal cells per hemisphere. The aDT2, aSP4 and vAB3 neurons show female-like arborisations in these males.

      The overall mating ability in competitive mating assays can be ranked as follows: fru[+] > fruΔA.T:Hsap\MYC > fruB2 > fruC1.
