Heterozygous flies show antenna to leg transformations.
Heterozygous adults show transformation of antenna to leg and the eyes are smaller than normal.
Heterozygotes lack the arista, but appear to have normal maxillary palps.
The locomotor activity of heterozygous flies in an open field arena is not significantly different from that of wild-type flies.
/+ mutants show ectopic transformation of antennae into leg tissue.
100% of heterozygotes show transformation of antenna to leg.
Only 15% of heterozygotes show normal arista development.
95% of mutant flies show an antenna to leg transformation.
Heterozygotes show transformation of antenna to leg.
96% of heterozygous flies show transformation of antenna to leg.
Antenna to leg transformation. Heterozygotes exhibit reduced compound eye and ommatidia are replaced by micro- and macrochaetae.
96-99% of heterozygotes show differentiation of leg structures in the antennae.
A viable dominant leg to antenna transformation.
derepresses the Antp
P2 promoter in the eye-antennal disc. The penetrance of antennae to leg transformations of AntpNs
mutations is greatly reduced in brm1
Partial transformation of antennae into legs. Flies exhibit diminished chemosensory jump behaviour to ethyl acetate but no change in the jump response to a visual stimulus.
Transformation of head to thoracic tissue.
Antennae to leg transformation.
Transformation of antenna to prothoracic leg identity.
In extreme cases, AntpNs
/+ forms, in place of an antenna, a complete leg that includes sternopleura, coxa, trochanter, femur, tibia, and tarsus. Antennal leg has no sex comb in male, and bristle pattern is that of a middle leg. Eyes smaller; whole head tends to be malformed. AntpNs ssa
indistinguishable from AntpNs
viable; phenotype like extreme AntpNs
/+. Expression variable but penetrance complete. RK1.
