Lack of degeneration of loci on the neo-Y chromosome of Drosophila americana americanaB Charlesworth
Department of Ecology and Evolution, University of Chicago, IL 60637 1573, USA
Genetics 145:989-1002. 1997..This is consistent with the recent origin of the neo-Y and neo-X chromosomes, and the slow rates at which the forces that cause Y chromosome degeneration are likely to work...
Recombination load associated with selection for increased recombinationB Charlesworth
Department of Ecology and Evolution, University of Chicago, IL 60637 1573, USA
Genet Res 67:27-41. 1996..Further experiments are needed to determine whether the selection against recombination due to the immediate load is outweighed by the increased additive variance in fitness produced by recombination...
Genetics of a pheromonal difference affecting sexual isolation between Drosophila mauritiana and D. sechelliaJ A Coyne
Department of Ecology and Evolution, University of Chicago, IL 60637, USA
Genetics 145:1015-30. 1997....
A selective sweep associated with a recent gene transposition in Drosophila mirandaS Yi
Department of Ecology and Evolution, University of Chicago, Chicago, Illinois 60637 1573, USA
Genetics 156:1753-63. 2000..This explanation is supported by the pattern of within-species sequence variation at exu1 and the nearby exu2 locus. The implications of this phenomenon for genome evolution are discussed...
The effect of recombination on background selectionM Nordborg
Department of Ecology and Evolution, University of Chicago, IL 60637 1573, USA
Genet Res 67:159-74. 1996..Large overall effects are less likely in species with higher levels of genetic recombination, such as mammals, although local reductions in regions of reduced recombination might be detectable...
The effects of local selection, balanced polymorphism and background selection on equilibrium patterns of genetic diversity in subdivided populationsB Charlesworth
Department of Ecology and Evolution, University of Chicago, IL 60637, USA
Genet Res 70:155-74. 1997..We discuss how these theoretical results can be related to data on genetic diversity within and between local populations of a species...
Mutation-selection balance and the evolutionary advantage of sex and recombinationB Charlesworth
Department of Ecology and Evolution, University of Chicago, IL 60637
Genet Res 55:199-221. 1990..Recombination is selectively disadvantageous when there is diminishing returns epistasis. These results are compared with the results of previous theoretical studies of this problem, and with experimental data...
The pattern of neutral molecular variation under the background selection modelD Charlesworth
Department of Ecology and Evolution, University of Chicago, Illinois 60637 1573, USA
Genetics 141:1619-32. 1995..It remains to be decided whether background selection is sufficient to explain the observed extent of reduction in diversity in regions of restricted recombination...
Contrasting patterns of molecular evolution of the genes on the new and old sex chromosomes of Drosophila mirandaS Yi
Department of Ecology and Evolution, University of Chicago, IL 60637, USA
Mol Biol Evol 17:703-17. 2000..This is not expected under a model where the faster evolution of the X chromosome is postulated to be the main force driving the degeneration of the Y chromosome...
The effects of spontaneous mutation on quantitative traits. II. Dominance of mutations with effects on life-history traitsD Houle
Department of Ecology and Evolution, University of Chicago, IL 60637 1573, USA
Genet Res 70:27-34. 1997..These results are consistent with those of many other studies that suggest that both unselected mutations and those found segregating in natural populations are partially recessive...
Evidence for selection at the fused locus of Drosophila virilisJ Vieira
Institute of Cell, Animal and Population Biology, University of Edinburgh, Edinburgh EH9 3JT, United Kingdom
Genetics 155:1701-9. 2000..Our results suggest that the fused alanine haplotypes have recently increased in frequency in the D. virilis population...
X chromosome DNA variation in Drosophila virilisJ Vieira
Institute of Cell, Animal and Population Biology, University of Edinburgh, Ashworth Laboratories, UK
Proc Biol Sci 266:1905-12. 1999..There is no reduction in variation at two loci close to the centromeric heterochromatin, in contrast to Drosophila melanogaster...
How was the Sdic gene fixed?B Charlesworth
Nature 400:519-20. 1999
Genealogies and weak purifying selectionM Przeworski
University of Chicago, Illinois 60637, USA
Mol Biol Evol 16:246-52. 1999..We caution, however, that the effect of weak selection on the genealogy is specific to the model; a (more realistic) model of multiple linked sites could lead to a more distorted genealogy than is observed for a single site...
Measures of divergence between populations and the effect of forces that reduce variabilityB Charlesworth
Department of Ecology and Evolution, University of Chicago
Mol Biol Evol 15:538-43. 1998....
The changing sizes of genesB Charlesworth
Nature 384:315-6. 1996
The evolution of lethals in the t-haplotype system of the mouseB Charlesworth
Department of Ecology and Evolution, University of Chicago, Illinois 60637
Proc Biol Sci 258:101-7. 1994..The theoretical predictions are compared with data on natural populations...
Genome analysis: More Drosophila Y chromosome genesB Charlesworth
Institute of Cell, Animal and Population Biology, University of Edinburgh, Ashworth Laboratories, Edinburgh EH9 3JT, UK
Curr Biol 11:R182-4. 2001..The D. melanogaster genome sequence has now allowed characterization of two more male fertility genes, shedding light on the function and evolution of Y chromosomes...
Evidence for selection at the fused1 locus of Drosophila americanaJ Vieira
Institute of Cell, Animal and Population Biology, University of Edinburgh, Edinburgh EH9 3JT, United Kingdom
Genetics 158:279-90. 2001..These patterns of variation are best explained as a result of selection acting on amino acid substitutions, with geographic variation in selection pressures...
Steps in the evolution of heteromorphic sex chromosomesD Charlesworth
Institute of Evolutionary Biology, School of Biological Sciences, University of Edinburgh, King s Buildings, West Mains Road, Edinburgh, UK
Heredity (Edinb) 95:118-28. 2005..We discuss how selection during the period when a chromosome is adapting to its role as a Y chromosome might drive such a process...
