Heterozygotes are fertile and grow more slowly than gld-1(q266) homozygotes. gld-1(q266) homozygotes are sterile and produce small abnormal oocytes. nDf24 homozygotes are dead.

Heterozygotes are WT and segregate WT, sterile hermaphrodites (gld-1 homozygotes) and larvae that are often stuck in an old cuticle or have old cuticle attached to their posteriors (arrest by L4 stage).
