Homozygous lethal at 29oC. Homozygotes do not reach the late pupal stage. 7% of Nl1N-2/Nl1N-ts1 flies survive at 29oC. Phenotypes seen include fused stubby legs and no head. 50% of Nl1N-2/NAx-tsl flies survive at 29oC. Phenotypes seen include small eyes and head, an abruptex phenotype and fused legs.
Nl1N-2/+ females are wild type; Nl1N-2/N females and Nl1N-2/Y males are lethal. Heterozygotes with fa and Nfa-g are fa-like; with nd, they have nd-like wings and small eyes; with Nnd-3, they are viable, fertile and Nnd-3-like. Developmental defects in Nl1N-2/Y males and time of lethal effect same as in Nl1N-1/Y. Some Nl1N-2/Nl1N-ts1 females survive to late pupal stage (Shellenbarger and Mohler, 1975).
