|Title:||Estimating Genomic Variance Explained per Chromosome Using Pedigree and Genomic Data in Sheep||Contributor(s):||Esquivelzeta-Rabell, C (author); Moghaddar, Nasiroddin (author); Clark, Sam A (author) ; Van Der Werf, Julius H (author)||Publication Date:||2014||Handle Link:||https://hdl.handle.net/1959.11/18737||Abstract:||We used a half sib data structure for a growth trait in sheep as a potentially powerful design for partitioning the genetic variance across the different chromosomes. Records for post weaning weight were used from 2455 merino sheep. The model of analysis accounted for population structure by fitting genetic group effects as well as the numerator relationship matrix (A) based on pedigree. We then fitted the matrix D representing the difference between the genomic relationship matrix (G) and A. The matrix G was based on 48,599 SNP markers across the entire genome, or on all SNPs of an individual chromosome. There was a relationship between chromosome length (L) and variance explained (Vgi), but we found significant differences in (Vgi/L) between chromosomes.||Publication Type:||Conference Publication||Conference Name:||WCGALP 2014: 10th World Congress on Genetics Applied to Livestock Production, Vancouver, Canada, 17th - 22nd August, 2014||Conference Details:||WCGALP 2014: 10th World Congress on Genetics Applied to Livestock Production, Vancouver, Canada, 17th - 22nd August, 2014||Source of Publication:||Proceedings of the 10th World Congress on Genetics Applied to Livestock Production (WCGALP) (Methods and Tools: Statistical and genomic tools for mapping QTL and genes (Posters)), p. 1-3||Publisher:||American Society of Animal Science||Place of Publication:||Champaign, United States of America||Field of Research (FOR):||070201 Animal Breeding||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Other Links:||https://asas.org/docs/default-source/wcgalp-posters/685_paper_9974_manuscript_1678_0b.pdf||Statistics to Oct 2018:||Visitors: 285
