This paper presents results from a mapping experiment to detect quantitative trait loci (QTL) for resistance to Haemonchus contortus infestation in merino sheep. The primary trait analysed was faecal worm egg count in response to artificial challenge at 6 months of age. In the first stage of the ...

The genetic structure of sheep reflects their domestication and subsequent formation into discrete breeds. Understanding genetic structure is essential for achieving genetic improvement through genome-wide association studies, genomic selection and the dissection of quantitative traits. After ide...


Kijas, J.W.Townley, D.Dalrymple, B.P.Heaton, M.P.Maddox, J.F.[A Genome Wide Survey of SNP Variation Reveals the Genetic Structure of Sheep Breeds]A Genome Wide Survey of SNP Variation Reveals the Genetic Structure of Sheep Breeds

To date, investigations of genetic diversity and the origins of domestication in sheep have utilised autosomal microsatellites and variation in the mitochondrial genome. We present the first analysis of both domestic and wild sheep using genetic markers residing on the ovine Y chromosome. Analysi...
