Animal Science Conference Proceedings and Presentations

Advances in the fields of molecular genetics and genomics have been considerable over the past several years. Recent discoveries in human genetics and in molecular biology have led to the development of a very useful genetic map of the pig. Several recent quantitative trait loci (QTL) scans and candidate gene analyses have identified important chromosomal regions and individual genes associated with carcass and meat quality traits. The causative mutations for porcine stress syndrome (HAL or RYR1) and the acid meat (RN) disorder, both with effects on meat quality are now known. Candidate genes for carcass merit (MC4R) and meat quality ...

The techniques of molecular biology and molecular genetics have rapidly progressed. These methods, coupled with advances in human genetics, have opened new vistas for investigators wishing to identify genes that control quantitative traits (quantitative trait loci or QTL). Also, over the past years, a great deal of progress has been made in development of genetic maps in the pig. For example, a large international mapping effort (Archibald et al., 1994), a USDA/ARS effort (Rohrer et al., 1996) and a U.S. coordinated effort (Rothschild, 1994) have produced several genetic linkage maps for the pig. Based on these linkage maps ...
