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 ...

Selection for complex traits leaves little or no classic signatures of selection [PDF]
, 2014 BACKGROUND: Selection signatures aim to identify genomic regions underlying recent adaptations in populations. However, the effects of selection in the genome are difficult to distinguish from random processes, such as genetic drift.

Complex signatures of natural selection at GYPA [PDF]
Human Genetics, 2018 The human MN blood group antigens are isoforms of glycophorin A (GPA) encoded by the gene, GYPA, and are the most abundant erythrocyte sialoglycoproteins. The distribution of MN antigens has been widely studied in human populations yet the evolutionary and/or demographic factors affecting population variation remain elusive.

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 ...

Genome wide signatures of positive selection: The comparison of independent samples and the identification of regions associated to traits [PDF]
, 2009 Background The goal of genome wide analyses of polymorphisms is to achieve a better understanding of the link between genotype and phenotype. Part of that goal is to understand the selective forces that have operated on a population.

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 ...
