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 ...
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. ...
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 ...
Copia Retrotransposon in the Zaprionus Genus: Another Case of Transposable Element Sharing with the Drosophila melanogaster Subgroup
Copia is a retrotransposon that appears to be distributed widely among the Drosophilidae subfamily. Evolutionary analyses of regulatory regions have indicated that the Copia retrotransposon evolved through both positive ...
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 ...
