      Third instar homozygous larvae fail to pupariate and survive as wandering larvae for up to two weeks.

      The brains of homozygous and woc251/wocrgl larvae show a high frequency of telomere-telomere attachments compared to controls. Single telomere attachments in which a single telomere fuses with its sister telomere, or in which a single telomere fuses with another single nonsister telomere are both seen. Double telomere attachments, where a pair of sister telomeres join with another pair are seen; both monocentric ring chromosomes and linear dicentric chromosomes are seen. In addition, multiple double telomere attachments, resulting in multicentric rings or linear chromosomes, are also seen. The average number of telomere-telomere attachments per cell is 2.00 in homozygotes and 1.94 in woc251/wocrgl animals.

      Polytene chromosomes derived from homozygous larvae are thinner than their wild-type counterparts but show an overall normal banding pattern.

      The frequency of telomere-telomere attachments seen in the brains of woc251 Lig411 double mutant larvae is not significantly different from that found in woc251 single mutants.
