One of the main objectives of rainbow trout genomic research is the development of rapid, accurate and automated genotyping systems for sequence variations influencing economically important traits.
The aim of this study was to combine two F2 designs produced independently in France and in the Netherlands to detect QTL influencing economically important traits.
Linkage maps, based primarily on highly polymorphic, anonymous microsatellite markers, have been important for identifying chromosomal regions influencing economically important traits in cattle [ 1- 3].
Thus, mapping signatures of selection may not be a very effective alternative to GWAS for the identification of genomic regions influencing economically important traits, as the peculiar structure of livestock populations generates high background.
Even after the bovine genome is completely sequenced, the map will continue to be a useful tool to link observable phenotypes and animal genotypes to underlying genes and molecular mechanisms influencing economically important beef and dairy traits.
The genetic map, especially if it is continually updated to represent new SNPs and other markers, should provide valuable links between phenotypes and associated marker genotypes, in order to identify and exploit genomic variation influencing economically important traits.
The map can easily be updated with a cyclic map construction process, and it will continue to be a useful resource connecting observable phenotypes and animal genotypes to underlying genes and molecular mechanisms influencing economically important beef and dairy traits.
Even after the salmon genome is completely sequenced, the map will continue to be a useful tool to link observable phenotypes and animal genotypes to underlying genes and molecular mechanisms influencing economically important traits.
At the core of their legal challenge will be the argument that the Environmental Protection Agency EPAA) does not have such broad authority to influence the economically crucial area of energy policy.
