Detailed Description
Statement
Reference

N55e11 hemizygous males bearing one copy of Ngt-16-20 show wing vein loss, as compared to controls.

Animals lacking endogenous N (Df(1)N-54l9/Y) and rescued by one copy of Ngt-16-20 exhibit a partial loss of wing veins L2, L4 and L5 at 25[o]C, as well as head bristle defects at 30[o]C.
