Heredity (Edinb)
. 1998 Nov;
81 ( Pt 3):246-53.
PMID: 9800368
Using an isofemale line analysis, we analysed the consequences of extreme rearing temperatures for genetic variation in quantitative characters in Drosophila melanogaster. Three types of characters were used: life history...

Genet Res
. 1998 Aug;
71(3):247-56.
PMID: 9717440
We use modifier theory to compare the evolution of recombination under mutation-selection and migration-selection balance models. Recombination between loosely linked loci subject to weak multilocus selection is controlled by the...

Mol Biol Evol
. 1997 Sep;
14(9):926-33.
PMID: 9287425
Mutation bias is one of the forces that may constrain the variation at microsatellite loci. Here, we study the dynamics of population statistics and the genetic distance between two populations...

EXS
. 1997 Jan;
83:241-54.
PMID: 9342852
A haploid population subject to recurrent deleterious mutations and two environments that provide two different profiles of selection coefficients over loci are modeled. The population is supposed to inhabit one...

Zhivotovsky L, Feldman M, Bergman A
Genet Res
. 1996 Dec;
68(3):241-8.
PMID: 9062081
We analyse patterns of the means and variances of genotypic fitnesses across different niches in a randomly mating haploid population. The population inhabits a spatially heterogeneous environment where it is...

Mol Biol Evol
. 1996 Nov;
13(9):1213-8.
PMID: 8896373
It has recently been suggested that observed levels of variation at microsatellite loci can be used to infer patterns of selection in genomes and to assess demographic history. In order...

Proc Natl Acad Sci U S A
. 1995 Dec;
92(25):11549-52.
PMID: 8524801
We analyze the within- and between-population dynamics of the distribution of the number of repeats at multiple microsatellite DNA loci subject to stepwise mutation. Analytical expressions for moments up to...

Theor Popul Biol
. 1995 Apr;
47(2):244-56.
PMID: 7740441
In diploid random mating populations with constant viability selection, genetic modifiers of recombination, introduced near equilibria that exhibit genetic association, invade if they reduce recombination. In this study we combine...

Genetica
. 1995 Jan;
96(3):303-6.
PMID: 8522169
Genetic variation of a suite of 12 morphometric wing characters was examined in 16 natural populations of Drosophila melanogaster from Eastern Europe and Central Asia using principal component analysis. The...

Proc Natl Acad Sci U S A
. 1994 Feb;
91(3):1079-83.
PMID: 8302835
Conditions for invasion by a new allele that controls the recombination pattern among an arbitrary number of genes under viability selection are studied. The recombination pattern may include interference. The...
