bip24 mutants are late embryonic or first instar larval recessive lethal, without any obvious morphological defects.
Approximately 4% in AntpCtx/+;bip24/+ transheterozygous flies. Flies showing an ectopic wing on the head almost always show a normal or slightly reduced eye, whereas flies with a head capsule-to-thorax transformation mostly have reduced or lost eyes.
AntpCtx/+;bip24/+ flies show strong eye-reduction/eye-loss phenotypes. Thirty-four percent of the eyes of AntpCtx/+;bip24/+ flies show an eye-loss phenotype, compared with 2% without the bip24 mutation.
