Homozygotes and hemizygotes display a severe 'flb' phenotype. Embryos produced from heteroallelic combination with Egfrt1 have a severe ventralised phenotype, reduction in size of their dorsal appendage.
Class I allele. This allele was originally thought to be a class IV allele, but the weak wing venation abnormalities observed for the allele were due to suppression by a px mutation on the same chromosome.
Mutation of Egfr that affects the gene function required for imaginal disc derivatives, a class IV lesion.
