    Detailed Description
    Statement
    Reference

    Khc16/+; Dp(1;2;Y)w+/+ larvae display strong axon clog and locomotion phenotypes, while Khc16/+; Tp(1;3)wvco/+ larvae display only the axon clog phenotype.

    Heterozygous larvae show normal locomotion. Some axonal swellings are seen in the segmental nerves of heterozygous larvae.

    Khc16/+ larvae that are also heterozygous for one of Df(3L)81k19, Df(3L)tra, Df(3L)st-b11, Df(3L)st-E36, Df(3L)st-j7 or In(3L)std11 develop numerous large axonal swellings and show paralytic tail flipping.

    Khc16/+ ; Abl1/+ double heterozygous larvae show posterior paralysis or "tail-flipping" and show an increase in the size and abundance of axonal swellings.

    Khc16/ena210 ; Abl1/+ triple heterozygous larvae do not show a tail-flipping phenotype and there is a marked reduction in axonal swellings compared to Khc16/+ ; Abl1/+ double heterozygous larvae.

    Khc16 shows a posterior paralysis phenotype in larvae in double heterozygous combination with Df(3L)34ex5, Gl1, E(Khc)ek2ek2, E(Khc)ek3ek3, Aplip1EK4, E(Khc)ek5ek5, E(Khc)ek6ek6, E(Khc)ek7ek7, E(Khc)ek8ek8, E(Khc)ek9ek9, E(Khc)ek10ek10 or Dhc64Cek1. The number of axonal swellings seen in Khc16 heterozygotes is dramatically increased if the larvae are also heterozygous for either Df(3L)34ex5, Dhc64Cek1 or Gl1. The axon swellings seen in double heterozygotes are rescued by Khc+t7.5.
