|Title:||The importance of population structure on the accuracy of genomic prediction in a multi-breed sheep population||Contributor(s):||Daetwyler, H D (author); Kemper, K E (author); Van Der Werf, Julius H (author) ; Hayes, B J (author)||Publication Date:||2011||Handle Link:||https://hdl.handle.net/1959.11/10101||Abstract:||Population structure, due to breed, strains and sire family, influences the accuracy of genomic prediction. We investigated principle component analysis as a way to account for population structure in within and across breed genomic prediction of greasy fleece weight and eye muscle depth in multi-breed sheep data. Population structure (including for example half sib family relationships) is responsible for a large proportion of the accuracy of genomic prediction. Correcting for it increased accuracy of greasy fleece weight across breed prediction, but reduced accuracy of across breed prediction for eye muscle depth for breeds not in the reference set. However, the correction reduced within breed accuracy.||Publication Type:||Conference Publication||Conference Details:||19th Conference of the Association for the Advancement of Animal Breeding and Genetics, Perth, Australia, 19th - 21st July, 2011||Source of Publication:||Breeding Objectives: A New Paradigm, p. 327-330||Publisher:||AAABG: Association for the Advancement of Animal Breeding and Genetics||Place of Publication:||Perth, Australia||Field of Research (FoR) 2008:||070201 Animal Breeding||Socio-Economic Objective (SEO) 2008:||830310 Sheep - Meat||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Other Links:||http://trove.nla.gov.au/work/162660639
