Detailed Description
Statement
Reference

Motor axons of intersegmental nerve b (ISNb) in for20-29/for20-29 or for20-29/+ mutant embryos display increases in targeting defects (overgrowth, targeting of incorrect muscles resulting in ectopic nerve endings, occasional abnormal associations with adjacent axons) compared to wild type.
