Signature of balancing selection in Arabidopsis [PDF]

Proceedings of the National Academy of Sciences, 2002
Natural selection and genetic linkage cause DNA segments to have genealogical histories resembling those of the selected sites. When a polymorphism maintained by selection is old, it will have an island of enhanced sequence variability surrounding it, which represents a detectable “signature of selection.” We investigate the ...

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.

Assessing the Genetic Background and Selection Signatures of Huaxi Cattle Using High-Density SNP Array

Animals, 2021
Simple Summary Evaluating population genetic background and genomic selection signatures can provide important insights into the uniqueness and the genetic relationship among breeds. In this study, we analyzed the genetic diversity, population structure,

Selecting reference signatures for on-line signature verification [PDF]

, 1995
Personal stability in signing in one of the key factors for high-accuracy signature verification. In this paper the local stability of a dynamic signature is measured. The acccuracy of an on-line signature verification system is improved by selecting, among a set of specimens available, the subset of reference signatures which is near-optimal for ...

Whole‐genome SNP markers reveal conservation status, signatures of selection, and introgression in Chinese Laiwu pigs

Evolutionary Applications, 2021
Laiwu pigs are a Chinese indigenous breed that is renowned for its exceptionally high intramuscular fat content (average greater than 6%), providing an excellent genetic resource for the genetic improvement of meat quality of modern commercial pigs.

The Cure: Making a game of gene selection for breast cancer survival prediction [PDF]

, 2014
Motivation: Molecular signatures for predicting breast cancer prognosis could greatly improve care through personalization of treatment. Computational analyses of genome-wide expression datasets have identified such signatures, but these signatures leave

Genome-Wide Analysis Reveals Selection Signatures Involved in Meat Traits and Local Adaptation in Semi-Feral Maremmana Cattle

Frontiers in Genetics, 2021
The Maremmana cattle is an ancient Podolian-derived Italian breed raised in semi-wild conditions with distinctive morphological and adaptive traits. The aim of this study was to detect potential selection signatures in Maremmana using medium-density ...

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 ...
