Sheep Genome Team

UK Sheep Genome Mapping Project

Aims

The project aims to apply genome mapping research to sheep, utilising previous research in sheep (in other countries) and in other species (in the UK and abroad) to the benefit of the UK sheep industry.  The project itself uses existing breeding structures, knowledge of the sheep genome and experimental resources.  It has three main aims: 

i) To use the Suffolk, Texel and Charollais Sire Referencing Schemes to detect and verify quantitative trait loci (QTLs) for growth and carcass composition traits 

ii) To investigate candidate genes and/or chromosomal regions for associations with production traits.

iii) To investigate approaches for optimising future genotyping strategies within the sire referencing schemes for practical and cost effective application of marker-assisted selection

By using commercial breeding populations for the research, immediate application of beneficial results is possible.  Potential benefits include increased genetic progress through marker assisted selection which utilises the genotype information, correction of possible parentage errors (ultimately leading to additional genetic progress) and opportunities for using marker information for product certification.
