Why is most of the genetic variance for complex traits undetected by large powerful screens of common variants? The genomics revolution has made it possible to measure thousands of DNA variants in individuals. These variants have been associated with phenotypic outcomes in a range of species. Paradoxically, even very large studies have only accounted for a fraction of the resemblance between relatives that we know exist. Our study will test three specific hypotheses to explain this paradox. A be ....Why is most of the genetic variance for complex traits undetected by large powerful screens of common variants? The genomics revolution has made it possible to measure thousands of DNA variants in individuals. These variants have been associated with phenotypic outcomes in a range of species. Paradoxically, even very large studies have only accounted for a fraction of the resemblance between relatives that we know exist. Our study will test three specific hypotheses to explain this paradox. A better understanding about the genetic architecture for complex traits will improve the efficiency of gene mapping methods, including applications in humans for traits related to productive ageing and a healthy start to life, will lead to more efficient selection programs in agricultural populations and will inform us with respect to past evolutionary events.Read moreRead less
The Relevance of the Bovine Major Histocompatibility Complex (MHC) to Milk Production. The objective of this project is to provide the dairy industry with an integrated package that includes a ?dairy performance database? linked to DNA-based information to complement existing breeding practices. Our intention is increase the profitability of the dairy industry, hence making a dairy farm a sustainable venture in a deregulated environment.

The objective of this project is to provide the dairy industry with an integrated package that includes a ?dairy performance database? linked to DNA-based information to complement existing breeding practices. Our intention is increase the profitability of the dairy industry, hence making a dairy farm a sustainable venture in a deregulated environment. Profitability results from a combination of several factors. The drivers of the industry include political, market, environmental, husbandry, nutrition, and genetic factors. These factors are interrelated. In this proposal, we are specifically interested in the relationship between milk yields and the DNA profile of dairy cattle.Read moreRead less
