Abstract

Methods to detect structural differences in specific genes provide qualitative inform ation on the nature o f genetic differences in dairy cattle. Using inform ation on genotypes determ ined by techniques used to investigate m olecular biology has been suggested to im prove selection accuracy fo r you n g anim als prior to perform ance recording or progeny information. Current evidence w ou ld suggest that structural differences are available as marker genes and that at least som e of these differences are related to quantitative traits. Estimates o f the size of these quantitative differences and statistical models to incorporate this data for maximum selection gains are needed.
