Fig. 2.

QTLs were mapped based on the amount of pollen stored in combs of colonies and confirmed based on individual behavior. Solid bars represent linkage groups with markers. Markers used in confirmation studies are shown. Orthologs of fly genes are indicated with arrows. Dashed lines indicate 97% CIs. Sequenced markers are underlined. No figure is shown for pln-4 because it was mapped by association to one marker (AmFOR) rather than by interval mapping. aPln-1 Map on the left is the localization of the QTL based on colony pollen stores. Map on the right is based on response thresholds to sucrose of individual worker bees. bPln-2QTL map on the left is based on colony pollen stores in a cross between European strains and the map on the right is based on a European by African strain cross. cPln-3QTL map is based on colony pollen stores
