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.

Cross-population selection signatures in Canchim composite beef cattle.

PLoS ONE, 2022
Analyses of livestock genomes have been used to detect selection signatures, which are genomic regions associated with traits under selection leading to a change in allele frequency.

Whole genome sequencing of Luxi Black Head sheep for screening selection signatures associated with important traits [PDF]

Animal Bioscience, 2022
Objective Luxi Black Head sheep (LBH) is the first crossbreed specialized for meat production and was developed by crossbreeding Black Head Dorper sheep (DP) and Small Tailed Han sheep (STH) in the farming areas of northern China. Research on the genomic

SNP Markers: Analysis of Genetic Diversity and Identification of Genomic Regions in Pantaneiro Sheep and Texel Sheep Under Natural Selection

Frontiers in Bioscience-Scholar
Background: Sheep farming is growing substantially in Brazil, driven by the increasing demand for sheep meat. This rising demand has heightened the focus on sheep, making them the subject of numerous studies, including those centered ...

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 ...

The study of selection signature and its applications on identification of candidate genes using whole genome sequencing data in chicken—a review

Poultry Science, 2023
: Chicken is a major source of protein for the increasing human population and is useful for research purposes. There are almost 1,600 distinct regional breeds of chicken across the globe, among which a large body of genetic and phenotypic variations has

Model selection and robust inference of mutational signatures using Negative Binomial non-negative matrix factorization

BMC Bioinformatics, 2023
Background The spectrum of mutations in a collection of cancer genomes can be described by a mixture of a few mutational signatures. The mutational signatures can be found using non-negative matrix factorization (NMF).

Evidence of positive selection towards Zebuine haplotypes in the BoLA region of Brangus cattle

Animal, 2018
The Brangus breed was developed to combine the superior characteristics of both of its founder breeds, Angus and Brahman. It combines the high adaptability to tropical and subtropical environments, disease resistance, and overall hardiness of Zebu cattle

Assessing Genomic Diversity and Productivity Signatures in Dianzhong Cattle by Whole-Genome Scanning

Frontiers in Genetics, 2021
Dianzhong cattle is a classic Chinese indigenous cattle breed with historical records dating back to 200 BC. But with its genomic differences having not been clearly elucidated, the quest for genomic characterization will be an essential step towards ...
