Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]
, 2020 Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Multi-locus analysis of genomic time series data from experimental evolution. [PDF]
, 2015 Genomic time series data generated by evolve-and-resequence (E&R) experiments offer a powerful window into the mechanisms that drive evolution. However, standard population genetic inference procedures do not account for sampling serially over time ...

Experimental harvesting of fish populations drives genetically based shifts in body size and maturation [PDF]
, 2013 Size-selective harvesting in commercial fisheries can induce rapid changes in biological traits. While experimental and wild harvested populations often exhibit clear shifts in body size and maturation associated with fishing pressure, the relative ...

Genome-Wide Footprints of Pig Domestication and Selection Revealed through Massive Parallel Sequencing of Pooled DNA [PDF]
, 2011 Background Artificial selection has caused rapid evolution in domesticated species. The identification of selection footprints across domesticated genomes can contribute to uncover the genetic basis of phenotypic diversity.

How Common Are Overdominant Mutations? [PDF]
Genetics, 2004 RECENTLY, [Peters et al. (2003)][1] reported that hybrids between EMS-mutagenized lines of Caenorhabditis elegans and the ancestral line in some cases had higher productivity and relative fitness than either parental line.

Segregation and the Evolution of Sex Under Overdominant Selection [PDF]
Genetics, 2003 Abstract The segregation of alleles disrupts genetic associations at overdominant loci, causing a sexual population to experience a lower mean fitness compared to an asexual population. To investigate whether circumstances promoting increased sex exist within a population with heterozygote advantage, a model is constructed that monitors ...

Experimental evaluation does not reveal a direct effect of microRNA from the callipyge locus on DLK1 expression [PDF]
, 2014 peer reviewedBACKGROUND: Polar overdominance at the ovine callipyge (CLPG) locus involves the post-transcriptional trans-inhibition of DLK1 in skeletal muscle of CLPG/CLPG sheep.

Estimation of Selection Intensity under Overdominance by Bayesian Methods [PDF]
Statistical Applications in Genetics and Molecular Biology, 2009 A balanced pattern in the allele frequencies of polymorphic loci is a potential sign of selection, particularly of overdominance. Although this type of selection is of some interest in population genetics, there exists no likelihood based approaches specifically tailored to make inference on selection intensity.

BMC Plant Biology, 2018 As a unique biological phenomenon, heterosis has been concerned with the superior performance of the heterosis than either parents. Despite several F1 hybrids, containing supernal nicotine content, had been discovered and applied to heterosis utilization
