“…Natural populations of D. melanogaster harbour a wealth of genetic variation, which has been proven to constitute a powerful resource to detect the genetic architecture for a wide range of phenotypes (Huang et al, 2014;King, Macdonald, & Long, 2012;MacKay et al, 2012). The Drosophila Genetic Reference Panel (DGRP), a population consisting of more than 200 highly inbred D. melanogaster strains derived from the Raleigh, US population (Huang et al, 2014;MacKay et al, 2012), has been successfully exploited to identify the association between a broad range of phenotypes and their underlying genetic basis, including several behavioural traits (Lee et al, 2017;Rohde, Gaertner, Ward, Sørensen, & Mackay, 2017;Shorter et al, 2015;Xue, Wang, & Zhu, 2017). The highly inbred nature of these DGRP strains allows accurate association mapping, through repeatedly sampling for individuals with the same genotype.…”
