Population genetics: The signature of selection [PDF]
Current Biology, 2001 There is hope that the structure of molecular variation within populations can give evidence for recent adaptive evolution. New work on Drosophila genes that seem to have been subject to adaptive changes illustrates the difficulties in calculating the statistical significance of data trends that seem to show this.

An insight into the runs of homozygosity distribution and breed differentiation in Mangalitsa pigs
Frontiers in Genetics, 2022 Mangalitsa pigs exhibit three distinct coat color patterns based on which they are described as Red, Blond, and Swallow-bellied. The current study investigated genome-wide diversity and selection signatures in the three breeds using fixation index, runs ...

Molecular Signatures of Natural Selection [PDF]
Annual Review of Genetics, 2005 There is an increasing interest in detecting genes, or genomic regions, that have been targeted by natural selection. The interest stems from a basic desire to learn more about evolutionary processes in humans and other organisms, and from the realization that inferences regarding selection may provide important functional information.

BMC Evolutionary Biology, 2019 Background Lodgepole pine (Pinus contorta) and interior spruce (Picea glauca, Picea engelmannii, and their hybrids) are distantly related conifer species. Previous studies identified 47 genes containing variants associated with environmental variables in

Linkage Disequilibrium as a Signature of Selective Sweeps [PDF]
Genetics, 2004 Abstract The hitchhiking effect of a beneficial mutation, or a selective sweep, generates a unique distribution of allele frequencies and spatial distribution of polymorphic sites. A composite-likelihood test was previously designed to detect these signatures of a selective sweep, solely on the basis of the spatial distribution and ...

Bidirectional Selection for Body Weight on Standing Genetic Variation in a Chicken Model
G3: Genes, Genomes, Genetics, 2019 Experimental populations of model organisms provide valuable opportunities to unravel the genomic impact of selection in a controlled system. The Virginia body weight chicken lines represent a unique resource to investigate signatures of selection in a ...

The effect of divergent selection for intramuscular fat on the domestic rabbit genome
Animal, 2020 An experiment of divergent selection for intramuscular fat was carried out at Universitat Politècnica de València. The high response of selection in intramuscular fat content, after nine generations of selection, and a multidimensional scaling analysis ...

A Meta-Assembly of Selection Signatures in Cattle
PLOS ONE, 2016 Since domestication, significant genetic improvement has been achieved for many traits of commercial importance in cattle, including adaptation, appearance and production. In response to such intense selection pressures, the bovine genome has undergone changes at the underlying regions of functional genetic variants, which are termed "selection ...
