Gene mapping in Soay sheep by linkage and linkage disequilibrium analysis

We are investigating the genetic architecture of fitness-related traits in a free-living population of Soay sheep on the remote Scottish archipelago of St. Kilda. The team are split between the Institute of Cell, Animal and Population Biology at the University of Edinburgh and the Department of Animal and Plant Sciences, University of Sheffield.

The main aim of this component of the project is to identify, type and analyse single nucleotide polymorphisms (SNPs) in various regions of the Soay sheep genome. Genomic regions of interest will include (1) regions known to be segregating for quantitative trait loci (QTL) for fitness-related traits and (2) genes known to cause variation in fecundity and growth in domestic sheep. Collaborators in Edinburgh will be using microsatellites to linkage map QTL for fitness traits in the study population.
