      Reference

      Homozygotes and Df(3R)opaB3-2/opa1 heterozygotes display a cuticular phenotype indistinguishable from opa1 homozygotes, embryo has half the number of normal body segments and each is roughly twice the normal width. At embryonic stage 16 none of the three midgut constrictions have formed.
