Population structure of eleven Spanish ovine breeds and detection of selective sweeps with BayeScan and hapFLK

Abstract: The goals of the current work were to analyse the population structure of 11 Spanish ovine breeds and to detect genomic regions that may have been targeted by selection. A total of 141 individuals were genotyped with the Infinium 50 K Ovine SNP BeadChip (Illumina). We combined this dataset with Spanish ovine data previously reported by the International Sheep Genomics Consortium (N = 229). Multidimensional scaling and Admixture analyses revealed that Canaria de Pelo and, to a lesser extent, Roja Mallorquina, L… Show more

“…Since the dawn of agriculture, artificial selection has continuously added to the existing pool of phenotypic variation as same as natural selection fuels the generation of biodiversity on earth. The programs of selection signature have identified hundreds of regions or genes targeted by important traits that formed by natural or artificial selection inchicken8, cattle6, swine11 and sheep12. It’s essential to identify candidate genes of important economic traits used for further studies in goats.…”

“…Instead, we used previously published Illumina Ovine SNP50 BeadChip data from 141 sheep corresponding to the Segureña ( n = 12), Xisqueta ( n = 24), Ripollesa ( n = 24), Gallega ( n = 25), Canaria de Pelo ( n = 27) and Roja Mallorquina ( n = 29) breeds (Manunza et al . ). Genotypic data from 279 sheep belonging to the Ojalada ( n = 24), Castellana ( n = 23), Rasa Aragonesa ( n = 22), Churra ( n = 120) and Latxa ( n = 90) breeds provided by the International Sheep Genomics Consortium (http://www.sheephapmap.org/) were also included.…”

“…In a previous study, Manunza et al . () characterized the diversity of 11 ovine Spanish breeds and detected several putative selective sweeps on ovine chromosomes 3, 6 and 13. Here, we aimed to analyze the patterns of homozygosity of these 11 sheep breeds to make inferences about their demographic history.…”

“…The availability of powerful and cheap tools for genotyping large numbers of single nucleotide polymorphisms (SNPs) has provided conservation biologists and animal geneticists with the opportunity to characterise genomic variation and estimate population genetic parameters at very high resolution in threatened or endangered livestock breeds (Pertoldi et al, 2014; Ben Jemaa et al, 2015; Beynon et al, 2015; Meszaros et al, 2015; Burren et al, 2016; Decker et al, 2016; Iso-Touru et al, 2016; Manunza et al, 2016; Mastrangelo et al, 2016; Visser et al, 2016; Williams et al, 2016; Francois et al, 2017). These studies are already providing important baseline data for genetic conservation and will underpin programmes for managed breeding and biobanking of these populations (Groeneveld et al, 2016).…”
