Genetic location of wc: 3-3.8.
In situ hybridization of single copy w DNA to Tp(1;3)wc-1 locates the transposon at 62E; transposon associated with FB elements (Paro et al., 1983)
Male with w or Df(1)w is wc. Transposition recessive to w+, complements wsp. mutable (Green, 1969). homozygous lethal
Believed to be effect of transposing element, the distal part of the w locus being moved to chromosome 3.
