Abstract
Both analytical and molecular tools currently exist that can be used to prolifically apply quantitative trait loci QTL analysis to the study of natural populations In this communication we review and exemplify the use of QTL mapping tools and genetic modeling for conservation geneticists We simulate populations inspired by relevant cases that can be encountered in the field and analyze them using the recently developed flexible intercross analysis FIA method We then reanalyze these results with the also recently developed natural and orthogonal interactions NOIA model of genetic effects Next we further exemplify the potential of genetic modeling for the interpretation of the output of QTL analyses by reviewing studies on hybrids between wild individuals and their domesticated relatives Based on the results here presented we emphasize several points that are pertinent in conservation genetics including i the advantages of FIA as a powerful tool to be applied to line crosses in which the parental lines are not inbred ii the importance of obtaining estimates of genetic effects that are adequate to address the research issue under consideration iii the versatility of genetic modeling particularly NOIA to dissect complex genetic architectures and iv the possibility of using currently available methods to address nonequilibrium multiallelic systemsÖrjan Carlborg Ania PinoQuerido and Lars Rönnegård and two reviewers have provided valuable comments on the manuscript JAC acknowledges funding by an “Isidro Parga Pondal” contract from the Xunta de Galicia ALR was funded by the Marie Curie Fellowship EIF220558
