A VARIABILIDADE POPULACIONAL DO ELEMENTO DE TRANSPOSIÇÃO mariner NA ESPÉCIE Drosophila simulans E SUA DESCOBERTA EM Drosophila melanogaster
(Universidade Federal de Santa MariaBRCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade Animal, 2009-10-09)
Transposable elements are DNA sequences that can change their location within the genome and can be found in almost all organisms. The mariner transposable element belongs to Class II, Tc1-mariner superfamily. An inactive ...
Distribution of the Bari-I transposable element in stable hybrid strains between Drosophila melanogaster and Drosophila simulans and in Brazilian populations of these species
(Sociedade Brasileira de Genética, 2007-01-01)
We analyzed the distribution of the Bari-I transposable element in Drosophila melanogaster (IN(1)AB), its sibling species Drosophila simulans (C167.4) and in eight hybrid strains derived from initial crosses involving D. ...
Biometrical analysis of larval digging behavior in Drosophila melanogaster
(Kluwer Academic Publishers-Plenum Publishers, 1994)
Digging behavior of D. melanogaster larvae increases as larval development proceeds. Diallel crosses were made to analyze genetically digging behavior at 72 and 108 h of larval age. Additive and dominance variation was ...
Selection for digging behavior in Drosophila melanogaster larvae
(Kluwer Academic Publishers-Plenum Publishers, 1978)
The genetics of the digging behavior of Drosophila melanogaster larvae was studied through selective breeding. Selection for low digging activity was successful, but selection for high digging activity was not. Selection ...
Inter- and intrapopulational variation in digging in Drosophila melanogaster larvae
(Kluwer Academic Publishers-Plenum Publishers, 1977)
The digging behavior of larvae from the following strains of Drosophila melanogaster was studied: Oregon R-c, taxi, yellow, and vestigial. It was found that the time of stay of preadults in the culture medium, the number ...
Genotoxicity testing of two lead-compounds in somatic cells of Drosophila melanogaster
The in vivo genotoxic activity of two inorganic lead compounds was studied in Drosophila melanogaster by measurement of two different genetic endpoints. We used the wing-spot test and the comet assay. The comet assay was ...
