The genetics of behaviour and other adaptive traits in nine-spined sticklebacks (Pungitius pungitius)
One of the main goals in current evolutionary biology research is to identify genes behind adaptive phenotypic variations. The advances in genomic technologies have made it possible to identify genetic loci behind these variations, also concerning non-model species. This thesis investigates the gene...

One of the main goals in current evolutionary biology research is to identify genes behind adaptive phenotypic variations.
