Quaas, Richard Louis
Professor
For 30 years my research has dealt with the problems of selecting livestock, mostly beef cattle, to meet the goals of their breeders through the application of statistics and quantitative genetics. Some was theoretical but with the idea that technology would be rapidly tranferred to the industry. More recently, in addition to utitlizing pedigree and phenotypic information. I am now involved with incorporating DNA marker information for into the process.
research
research and scholarship focus
I chair a committe of the National Beef Cattle Evaluation Consortium charged with validating commercial DNA tests for quantitative beef cattle traits. We attempt to replicate results claimed by genomics companies marketing the tests.Our purpse is two-fold: firstly, we provide third-party information to beef producers on efficacy. Secondly, we encourage the use of new technology by helping to assure the end users that it really does work, when it does.
