      Statement
      Reference

      Homozygotes display an intermediate 'flb' phenotype. Embryos produced from heteroallelic combination with Egfrt1 have a severe ventralised phenotype, reduction in size of their dorsal appendage. Individuals are fully viable over the pupal lethals Egfrtop-CA and Egfrtop-EC20 and show a reduction in viability over Egfrtop-EB.
