This is what will get me to Puerto Rico in june, I hope.

“Domestication is associated with strong selection and rapid phenotypic change. It therefore offers opportunities to study consistent directional selection on complex characters in organisms with long generation times. Contemporary domestications, additionally, also allow the early stages of the domestication process to be analysed.

Atlantic salmon (Salmo salar) was domesticated less than 15 generations ago. This recent domestication has targeted particularly body size as the major selective trait, but the commercial rearing environments have also been shown to be responsible for indirect selection on behavioural traits, e.g. reduced predator response and increased aggression. As the traits under selection are complex polygenic characters and the selection is likely on existing genetic variation, we expect to find many loci responding to selection.

We exploited early samples and the well documented pedigree from this domestication event to track the impact of selection in a commercial salmon breeding line. We find striking variation among generations in the distribution, identity and number of loci displaying generation to generation transmission ratio distortion. Our results are consistent with an early response to domestication where the entire genetic background is subtly transformed. Selective sweeps, such as have been observed in older domestications, would then occur later within this transformed genetic background.”

Also, this is the basis of my first paper, 1/3 of my PhD.
