Dosage Compensation of X-Linked Muller Element F Genes but Not X-Linked Transgenes in the Australian Sheep Blowfly. [PDF]
PLoS ONE, 2015 In most animals that have X and Y sex chromosomes, chromosome-wide mechanisms are used to balance X-linked gene expression in males and females. In the fly Drosophila melanogaster, the dosage compensation mechanism also generally extends to X-linked ...

Biochemical evidence of chromosome homoeology among related plant genera. [PDF]
, 1975 Biochemical markers associated with homoelogous chromosome groups 3 and 7 of Triticum aestivum L. have been investigated in genetic stocks carrying chromosomes or chromosomal segments of the same homoeology groups from Agropyron elongatum and Secale ...

THE NATURE OF QUANTITATIVE GENETIC VARIATION IN DROSOPHILA. III. MECHANISM OF DOSAGE COMPENSATION FOR SEX-LINKED ABDOMINAL BRISTLE POLYGENES [PDF]
Genetics, 1977 ABSTRACT Seventeen lines, each homozygous for a different × chromosome but all with a common autosomal genetic background, were constructed and assayed for abdominal bristle number to determine whether dosage compensation operates for sex-linked genes affecting this character.—The regression coefficient of male mean on female mean using ...

Effects of Gene Dose, Chromatin, and Network Topology on Expression in Drosophila melanogaster.
PLoS Genetics, 2016 Deletions, commonly referred to as deficiencies by Drosophila geneticists, are valuable tools for mapping genes and for genetic pathway discovery via dose-dependent suppressor and enhancer screens.

Sex Bias and Maternal Contribution to Gene Expression Divergence in Drosophila Blastoderm Embryos. [PDF]
PLoS Genetics, 2015 Early embryogenesis is a unique developmental stage where genetic control of development is handed off from mother to zygote. Yet the contribution of this transition to the evolution of gene expression is poorly understood.

Abnormal Action Potentials Associated with the Shaker Complex Locus of Drosophila [PDF]
, 1981 Intracellular recordings of action potentials were made from the cervical giant axon in Shaker (Sh) mutants and normal Drosophila. The mutants showed abnormally long delays in repolarization.

Absence of a Faster-X Effect in Beetles (Tribolium, Coleoptera)
G3: Genes, Genomes, Genetics, 2020 The faster-X effect, namely the rapid evolution of protein-coding genes on the X chromosome, has been widely reported in metazoans. However, the prevalence of this phenomenon across diverse systems and its potential causes remain largely unresolved ...

Complex Evolutionary History of the Y Chromosome in Flies of the Drosophila obscura Species Group. [PDF]
, 2020 The Drosophila obscura species group shows dramatic variation in karyotype, including transitions among sex chromosomes. Members of the affinis and pseudoobscura subgroups contain a neo-X chromosome (a fusion of the X with an autosome), and ancestral Y ...

G3: Genes, Genomes, Genetics, 2016 Theory makes several predictions concerning differences in genetic variation between the X chromosome and the autosomes due to male X hemizygosity. The X chromosome should: (i) typically show relatively less standing genetic variation than the autosomes,

The 5'-3' exoribonuclease pacman is required for epithelial sheet sealing in Drosophila and genetically interacts with the phosphatase puckered [PDF]
, 2008 Background information. Ribonucleases have been well studied in yeast and bacteria, but their biological significance to developmental processes in multicellular organisms is not well understood.
