Effects of hybridization on sea turtle fitness
Sea turtle hybridization is a common phenomenon in Brazil between loggerheads (Caretta caretta) and hawksbills (Eretmochelys imbricata) as well as between loggerheads and olive ridleys (Lepidochelys olivacea). In...

Life history trade-offs and response to selection on egg size in the polychaete worm Hydroides elegans
In order to examine the genetic relationships among life-history traits in a hermaphroditic species we used artificial selection for increased egg size and measured correlated responses across the life cycle o...

Open AccessNatural genetic variation in transcriptome reflects network structure inferred with major effect mutations: insulin/TOR and associated phenotypes in Drosophila melanogaster
A molecular process based genotype-to-phenotype map will ultimately enable us to predict how genetic variation among individuals results in phenotypic alterations. Building such a map is, however, far from str...

Open AccessSex-specific expression of alternative transcripts in Drosophila
Many genes produce multiple transcripts due to alternative splicing or utilization of alternative transcription initiation/termination sites. This 'transcriptome expansion' is thought to increase phenotypic co...

Open AccessIdentification of co-regulated transcripts affecting male body size in Drosophila
Factor analysis is an analytic approach that describes the covariation among a set of genes through the estimation of 'factors', which may be, for example, transcription factors, microRNAs (miRNAs), and so on,...

Microclinal variation for ovariole number and body size in Drosophila melanogaster in ‘Evolution Canyon’
Sites that display strong environmental contrasts in close proximity, such as ‘Evolution Canyon’ on Mt. Carmel, Israel, are natural theatres for investigating adaptive evolution in action. We reared Drosophila me...

Open AccessIntersection tests for single marker QTL analysis can be more powerful than two marker QTL analysis
It has been reported in the quantitative trait locus (QTL) literature that when testing for QTL location and effect, the statistical power supporting methodologies based on two markers and their estimated gene...

Tracking adaptive evolutionary events in genomic sequences
As more gene and genomic sequences from an increasing assortment of species become available, new pictures of evolution are emerging. Improved methods can pinpoint where positive and negative selection act in ...
