      Class i allele.

      (Davis, 2003.5.6)

      Heterozygotes show a quantitative effect on wing shape in intervein region D compared to wild type.

      (Palsson and Gibson, 2000)

      Hemizygotes are almost wild-type, but have a reduction in the number of marginal bristles on the alulae and along the posterior wing margin. Wing vein L5 is sometimes shortened.
