The level of enzyme was measured in third instar larvae, 6-today-old males and in larval fat bodies and alimentary canals. In Modern Genetic Analysis. Limits to Adaptation in asexual populations. Journal of Drsophila Science Drosophila melanogaster mutations suppressible by the suppressor of Hairy-wing are insertions of a 7.

Effects of transposable element insertions on RNA encoded by the white gene of Drosophila.

Drosophila melanogaster – Wikipedia

Unequal crossing-over associated with asymmetrical synapsis between nomadic elements in the Drosophila melanogaster genome. A technique for radiolabeling DNA restriction endonuclease fragments to high specific activity. Melanogaater of the white locus in Drosophila melanogaster. The Drosophila drosopphila suppressor of Hairy-wing protein binds to specific sequences of the gypsy retrotransposon. One line was found, however, in which the ADH level in the fat body is more than twice the level one would expect on the basis of the activity in alimentary canal.

The contribution of ecological genetics to evolutionary theory: The evolution of mutation rates: A dosage-sensitive modifier of retrotransposon-induced alleles of the Drosophila white locus. The relative quantities and catalytic activities of enzymes produced by alleles at the alcohol dehydrogenase locus in Drosophila melanogaster. Abstract The white-apricot w a allele differs from the wild-type white gene by the presence of vrosophila retrovirus-like transposable element copia within the transcription unit.

Characterization of Enhancer-of-White-Apricot in Drosophila Melanogaster

The activity of w a is reduced in trans by a semidominant mutation in the gene Enhancer-of-white-apricot E w a. Abraham I, Doane WW. This semidominant effect on pigmentation is correlated with srosophila corresponding decrease in white RNA having wild type structure, and flies homozygous for E w a have increased levels of aberrant RNAs.
