Population genetics of polymorphism and divergence.

Study of the association between DRD2 Gene Ser311Cys and GSTM1 Gene polymorphism in Schizophrenia

Introduction: Schizophrenia is a mental disorder affecting 1% of the world's population. Two of genes have been recognized to be involved in development of this disease: DRD2 and GSTM1. Methods: This case-control study included 100 patients suffering from schizophrenia who referred to Yazd Neuropsychiatry Hospital. Also, 100 healthy patients without schizophrenia were selected as the control g...

Molecular population genetics of male accessory gland proteins in the Drosophila simulans complex.

Accessory gland proteins are a major component of Drosophila seminal fluid. These proteins have a variety of functions and may be subject to sexual selection and/or antagonistic evolution between the sexes. Most population genetic data from these proteins are from D. melanogaster and D. simulans. Here, we extend the population genetic analysis of Acp genes to the other simulans complex species,...

Population genetics of speciation in two closely related wild tomatoes (Solanum section Lycopersicon).

We present a multilocus sequencing study to assess patterns of polymorphism and divergence in the closely related wild tomato species, Solanum peruvianum and S. chilense (Solanum section Lycopersicon, Solanaceae). The data set comprises seven mapped nuclear loci (approximately 9.3 kb of analyzed sequence across loci) and four local population samples per species that cover much of the species' ...

Adaptive Gene Expression Divergence Inferred from Population Genomics

Detailed studies of individual genes have shown that gene expression divergence often results from adaptive evolution of regulatory sequence. Genome-wide analyses, however, have yet to unite patterns of gene expression with polymorphism and divergence to infer population genetic mechanisms underlying expression evolution. Here, we combined genomic expression data--analyzed in a phylogenetic con...

Population Genomics: Whole-Genome Analysis of Polymorphism and Divergence in Drosophila simulans

The population genetic perspective is that the processes shaping genomic variation can be revealed only through simultaneous investigation of sequence polymorphism and divergence within and between closely related species. Here we present a population genetic analysis of Drosophila simulans based on whole-genome shotgun sequencing of multiple inbred lines and comparison of the resulting data to...
