• Genome‐wide association study of milk production traits in a crossbred dairy sheep population using three statistical models

    One year ago - By Animal Genetics

    Summary
    Milk production is one of the most important characteristics of dairy sheep, and the identification of genes affecting milk production traits is critical to understanding the genetics and improve milk production in future generations. Three statistical techniques, namely GWAS, ridge‐regression BLUP and BayesC
    , were used to identify SNPs in significant association with three milk production traits in a crossbred dairy sheep population. The results suggested that chromosomes 1, 3, 4, 5, 7 and 11 were likely to harbor genes important to milk production because these chromosomes had...

  • Genome‐wide detection of copy number variants in European autochthonous and commercial pig breeds by whole‐genome sequencing of DNA pools identified breed‐characterising copy number states

    One year ago - By Animal Genetics

    Summary
    In this study, we identified copy number variants in 19 European autochthonous pig breeds and in two commercial breeds that represent important genetic resources for this species. The genome of 725 pigs was sequenced using a breed‐specific DNA pooling approach obtaining an average depth per pool of 42×. This approach maximised CNV discovery as well as the related copy number states characterising, on average, the analysed breeds. By mining more than 17.5 billion reads, we identified a total of 9592 CNVs and 3710 CNV regions , with an average of 77 CNVRs per breed that were...
