Extract

Genetic improvement of livestock is largely the result of selection based on estimated breeding values (EBVs) calculated from data on phenotypes and pedigrees. This technology has been very successful without using data on the individual genes responsible for genetic variation. For several years experiments have mapped genes affecting economic traits or quantitative trait loci (QTL) to chromosomal regions using genetic markers. Unfortunately this information has not lead to a substantial increase in the rate of genetic improvement.
