Progress and prospects toward our understanding of the evolution of dosage compensation [PDF]
Chromosome Research, 2009 In many eukaryotic organisms, gender is determined by a pair of heteromorphic sex chromosomes. Degeneration of the non-recombining Y chromosome is a general facet of sex chromosome evolution.

Evolution of dosage compensation
Chromosome Research, 1996In polytene chromosome squashes from the fruit fly Drosophila melanogaster, the single, dosage-compensated X chromosome in males can be distinguished from the autosomes by the presence of an isoform of histone H4 acetylated at lysine 16, H4.Ac16. We have used H4.Ac16 as a marker to examine the evolving relationship between dosage compensation and sex ...

Evolution of dosage compensation under sexual selection differs between X and Z chromosomes [PDF]
Nature Communications, 2015 Complete sex chromosome dosage compensation has more often been observed in XY than ZW species. In this study, using a population genetic model and the chicken transcriptome, we assess whether sexual conflict can account for this difference.

Nature Structural and Molecular Biology, 2023 In mammals, X-chromosomal genes are expressed from a single copy since males (XY) possess a single X chromosome, while females (XX) undergo X inactivation.

Dosage compensation goes global
Current Opinion in Genetics & Development, 2007In many organisms, females have two X chromosomes whereas males have just one. This natural X chromosome monosomy is not lethal, because of dosage compensation. Although numerous elegant genetic, biochemical and cytological experiments have been used to build up the mechanistic framework describing this specialized transcriptional control, dosage ...

Chromatin Remodeling in Dosage Compensation
Annual Review of Genetics, 2005In many multicellular organisms, males have one X chromosome and females have two. Dosage compensation refers to a regulatory mechanism that insures the equalization of X-linked gene products in males and females. The mechanism has been studied at the molecular level in model organisms belonging to three distantly related taxa; in these organisms ...

A brief history of dosage compensation
Journal of Genetics, 2014In 1914, H. J. Muller postulated the origin of the Y chromosome as having resulted from restricted recombination between homologous sex chromosomes in the male and the accumulation of deleterious mutations. This evolutionary process leads to dosage compensation. This article lays out a brief history of dosage compensation in genetics.

Dosage compensation in Drosophila
Trends in Genetics, 1986Abstract Dosage compensation in Drosophila is accomplished by a twofold transcriptional hyperactivation of the male X relative to each female X chromosome. A number of chromosomal signals and control genes have been implicated in this process.

Gene Dosage Compensation in Drosophila Melanogaster
1987The comparative lack of sexual dimorphism of apricot and other [sex-linked] genes studied is due to "sex-limitation", i.e., to a compensatory influence of the dosage difference between the sexes in respect to other genes in the X-chromosome. The facts are of particular interest from an evolutionary standpoint.
