Detection of selection signatures in dairy and beef cattle using high-density genomic information [PDF]
, 2015 peer-reviewedBackground Artificial selection for economically important traits in cattle is expected to have left distinctive selection signatures on the genome. Access to high-density genotypes facilitates the accurate identification of

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 ...

Detection of selection signatures in Piemontese and Marchigiana cattle, two breeds with similar production aptitudes but different selection histories [PDF]
, 2015 Background Domestication and selection are processes that alter the pattern of within- and between-population genetic variability. They can be investigated at the genomic level by tracing the so-called selection signatures.

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.

Runs of homozygosity and signatures of selection: a comparison among eight local Swiss sheep breeds. [PDF]
, 2019 A dataset consisting of 787 animals with high-density SNP chip genotypes (346 774 SNPs) and 939 animals with medium-density SNP chip genotypes (33 828 SNPs) from eight indigenous Swiss sheep breeds was analyzed to characterize population structure ...

Unravelling selection signatures in a single dog breed suggests recent selection for morphological and behavioural traits [PDF]
, 2020 Strong selection has resulted in substantial morphological and behavioural diversity across modern dog breeds, which makes dogs interesting model animals to study the underlying genetic architecture of these traits.

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.

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 ...

Recent and Ancient Signature of Balancing Selection around the S-Locus in Arabidopsis halleri and A. lyrata [PDF]
, 2013 Balancing selection can maintain different alleles over long evolutionary times. Beyond this direct effect on the molecular targets of selection, balancing selection is also expected to increase neutral polymorphism in linked genome regions, in inverse ...
