TLDR
There used to be a broad split within the experimental genetics research community between those who did mechanistic research using homozygous laboratory strains and those who studied patterns of genetic variation in wild populations, but such burgeoning experimental strategies as genome-wide analysis of quantitative trait loci, genotype–phenotype associations, and the products of experimental evolution are now fostering a unification of experimental genetic research that strengthens its scientific power.Abstract:
There used to be a broad split within the experimental genetics research community between those who did mechanistic research using homozygous laboratory strains and those who studied patterns of genetic variation in wild populations. The former benefited from the advantage of reproducible experiments, but faced difficulties of interpretation given possible genomic and evolutionary complexities. The latter research approach featured readily interpreted evolutionary and genomic contexts, particularly phylogeny, but was poor at determining functional significance. Such burgeoning experimental strategies as genome-wide analysis of quantitative trait loci, genotype–phenotype associations, and the products of experimental evolution are now fostering a unification of experimental genetic research that strengthens its scientific power.read more

Adaptation of Drosophila to a novel laboratory environment reveals temporally heterogeneous trajectories of selected alleles
Pablo Orozco-terWengel,Martin Kapun,VIiola Nolte,Robert Kofler,Thomas Flatt,Christian Schlötterer +5 more
TL;DR: The data suggest that the genomic response to selection can involve a large number of selected SNPs that show unexpectedly complex evolutionary trajectories, possibly due to nonadditive effects.

TL;DR: The data show thatsex determination in zebrafish is polygenic and that different genes may influence sex determination in different strains or thatDifferent genes become more important under different environmental conditions.

A Guide for the Design of Evolve and Resequencing Studies
TL;DR: Computer simulations suggest that, with an adequate experimental design, E&R studies are a powerful tool to identify adaptive mutations from standing genetic variation and thereby provide an excellent means to analyze the trajectories of selected alleles in evolving populations.

A RAD-tag Genetic Map for the Platyfish (Xiphophorus maculatus) Reveals Mechanisms of Karyotype Evolution Among Teleost Fish
Angel Amores,Julian M. Catchen,Indrajit Nanda,Wesley C. Warren,Ron Walter,Manfred Schartl,John H. Postlethwait +6 more
TL;DR: These studies identify likely genome assembly errors, characterize chromosome fusion events, distinguish lineage-independent chromosome fusions, show that the teleost genome duplication does not appear to have accelerated the rate of translocations, and reveal the stability of syntenies and gene orders in teleost chromosomes over hundreds of millions of years.

Life-History Evolution and the Genetics of Fitness Components in Drosophila melanogaster
TL;DR: What has been learned about the evolution and genetics of life-history variation in D. melanogaster is reviewed by drawing on numerous sources spanning population and quantitative genetics, genomics, experimental evolution, evolutionary ecology, and physiology.

TL;DR: This study has demonstrated that careful use of a shared control group represents a safe and effective approach to GWA analyses of multiple disease phenotypes; generated a genome-wide genotype database for future studies of common diseases in the British population; and shown that, provided individuals with non-European ancestry are excluded, the extent of population stratification in theBritish population is generally modest.

TL;DR: Evidence is provided that the remaining heritability is due to incomplete linkage disequilibrium between causal variants and genotyped SNPs, exacerbated by causal variants having lower minor allele frequency than the SNPs explored to date.

Evolutionary Rate at the Molecular Level
TL;DR: Calculating the rate of evolution in terms of nucleotide substitutions seems to give a value so high that many of the mutations involved must be neutral ones.
