NET [net]
Lindsley & Grell, 1972, p. 170
location: 2-0.0 [to the left of a1; order with 1(2)g1 not known].
origin: Spontaneous.
discoverer: Bridges, 31c10.
phenotype: Wing veins form plexuslike net; first posterior cell between L3 and L4 widens toward tip; branch missing from posterior crossvein; all veins fused at base of wing, like bi. According to Waddington [1940, J. Genet. 41: 75-139 (fig.)], spaces form between epithelial layers owing to inadequate contraction during pupal period; spaces later fuse and form extra veins. RK1.
cytology: Locus of net lies between 21A1 and 21C1 (Lewis, 1945, Geneties 30: 137-66).
