摘要: The genetic architecture of behavioral traits is yet relatively poorly understood in most non-model organisms. Using an F2-intercross (n = 283 offspring) between behaviorally divergent nine-spined stickleback (Pungitius pungitius) populations, we tested for and explored the basis different with aid quantitative trait locus (QTL) analyses based on 226 microsatellite markers. behaviors were analyzed both separately (viz. feeding activity, risk-taking exploration) combined order to map composite type. Two significant QTL—explaining average 6 % phenotypic variance—were detected type experiment-wide level, located linkage groups 3 8. In addition, several suggestive QTL six other chromosome-wide level. Apart from providing evidence variation, results provide a good starting point finer-scale factors influencing variation stickleback.
