Inversion breakpoint in Antp.
Inversion breakpoint is 45kb upstream of the P2 start site.
Inversion between Doc{}sasDoc (in first intron of sas) and Doc{}AntpDoc (in first intron of Antp) causes an exchange between the proximal exons of Antp and sas.
Proximal inversion breakpoint is at map position +178-182.
100% of heterozygotes show transformation of antenna to leg.
Mutants show extensive transformation of antenna to leg.
Only 55% of heterozygotes show normal arista development.
100% of mutant flies show an antenna to leg transformation.
Heterozygous males do not show any change in the level of monoene cuticular hydrocarbons compared to wild-type males. Heterozygous females do not show any significant change in the level of monoene or 7,11-diene cuticular hydrocarbons compared to wild-type females.
No gross morphological defects in the brain are seen in homozygous embryos.
Antenna to leg transformation. Heterozygotes display minaturised maxillary palps, characterised by fewer bristles. Heterozygotes exhibit reduced compound eye and ommatidia are replaced by micro- and macrochaetae.
None of the ash2 alleles affect the expressivity or penetrance of the antenna to leg transformation.
pbhs.PB cannot redirect phenotype of antennae from ectopic leg to maxillary palp.
Shows a small patch of untransformed antennal tissue remaining on the homeotic femur. Size of this patch varies 6-fold across different genetic backgrounds. Effects of maternal parent, sex and sex-linkage have been observed.
Transformation of head to thoracic tissue.
Homeotic transformation of antennae to mesothoracic legs.
Antennae to leg transformation.
Transformation of antenna to prothoracic leg identity.
A strong allele.
