- Multipoint linkage disequilibrium mapping using multilocus allele frequency dataT Johnson
Rothamsted Research, Harpenden, and School of Biological Sciences, University of Edinburgh, West Mains Road, Edinburgh EH9 3JT, Scotland, UK
Ann Hum Genet 69:474-97. 2005..Depending on how we choose to measure information, allele frequency data at an additional approximately 18 or approximately 33 markers is needed to compensate for this loss of information...
- The approach to mutation-selection balance in an infinite asexual population, and the evolution of mutation ratesT Johnson
Institute of Cell, Animal and Population Biology, University of Edinburgh, UK
Proc Biol Sci 266:2389-97. 1999..This flux raises the mean fitness of the mutator subpopulation, and when this factor is taken into account, the frequency of the mutator may be more than an order of magnitude greater than recent theoretical work has suggested...
- MCALIGN2: faster, accurate global pairwise alignment of non-coding DNA sequences based on explicit models of indel evolutionJun Wang
Institute of Evolutionary Biology, School of Biological Sciences, University of Edinburgh, Edinburgh EH9 3JT, UK
BMC Bioinformatics 7:292. 2006..Unraveling the functional significance of non-coding DNA depends on how well we are able to align non-coding DNA sequences. However, the alignment of non-coding DNA sequences is more difficult than aligning protein-coding sequences...

Institute of Evolutionary Biology, School of Biological Sciences, University of Edinburgh, UK
Genetics 173:2091-101. 2006..Our five examples of vertebrate breeding systems suggest that due to the remarkably low variance in relatedness across the population, marker-based estimates may often have low power to address research questions of interest...
- MCALIGN: stochastic alignment of noncoding DNA sequences based on an evolutionary model of sequence evolutionPeter D Keightley
University of Edinburgh, School of Biological Sciences, Ashworth Laboratories, Edinburgh EH9 3JT, UK Peter Keightley_at_ed ac uk
Genome Res 14:442-50. 2004..We show that there is excellent agreement between true and estimated alignments over a wide range of sequence divergences, and that the method outperforms other available alignment methods...

Department of Zoology, University of British Columbia, Vancouver, British Columbia V6T 1Z4, Canada
Genetics 162:395-411. 2002..Again, this analysis relaxes the assumption made previously that selection against deleterious alleles is stronger than on beneficial alleles...
