ORENGO, Dorcas J.; HAUSCHTECK-JUNGEN, Elisabeth and MESTRES, Francesc. One-winged Drosophila subobscura: a phenotype with an obscure genetic basis. Braz. J. Genet. [online]. 1997, vol.20, n.3, pp.-. ISSN 0100-8455. http://dx.doi.org/10.1590/S0100-84551997000300001.
A line of one-winged Drosophila subobscura was studied. The absent wing is substituted by a bulky structure with macro and microchaetes, showing a thoracic appearance. Genetic crosses showed that there is no way to select for the trait by simple crossing. The number of one-winged flies in the various generations was always low. In one case a wingless fly was also obtained. The trait presents an unknown genetic pattern.
