Detailed Description
Statement
Reference

salmFCK-25/Df(2L)32FP-5 transheterozygous animals exhibit an overall reduction in antennal segment 2 (a2). In addition a2 appears to be fused to a3 and a portion of the stalk that connects a2 to antennal segment 3 (a3) is exposed. The circular outline of the joint between antennal segments 2 and 3 is also lost. Furthermore a3 is unable to rotate in a2. salm16/salmFCK-25 clones in the antenna appear normal.

Reference

In T(2;3;4)FCK-25/Df(2L)32FP-5 mutant animals (T(2;3;4)FCK-25 cause the alleles salmFCK-25 and salrFCK-25) the Johnston's organs develop abnormally and degenerate during pupal stages. Scolopidia do differentiate but develop at reduced numbers and are highly disorganised, and by adulthood, some mutant antenna with no scolopidia are seen. The joint between antennal segments 2 and 3 is missing, these segments are also fused. As a consequence mutant animals have conductive hearing defects.

100% of flies carrying T(2;3;4)FCK-25 and either Df(2L)FCK-20, In(2L)FCK-73 or Df(2L)32FP-5 lack the anterior notopleural macrochaetae and humeral chaetae, and ectopic chaetae are seen on the base of the first leg in 3.6%, 3.9% and 3.7% of flies respectively.
