Multi-Allelic Major Effect Genes Interact with Minor Effect QTLs to Control Adaptive Color Pattern Variation in Heliconius erato
Figure 5
The homologous position of the D color pattern gene in four different races of H. erato and its pleiotropic effect on forewing color pattern.
(A) The fine resolution map (over 600 Kb) of several co-dominant markers linked to the D color pattern gene across all our collection of crosses. The relative position and number of recombinant individuals for the eight co-dominant markers linked to the D color pattern gene (see Table S1) confirmed the homologous position of D across all H. erato races used in our crosses. The numbers within brackets in panel A represent the total number of recombinant individuals generated by combining the information from all crosses (Table S1). (B) The linkage analysis of LG 18 in the F2-Not9 cross and the relative position of the D locus on the chromosome, including the position and name of AFLP loci, two of the eight co-dominant markers (D23/24 and optix) and the D locus along the chromosome. (C) QTL analysis for the forewing band color (red and/or white) on LG 18. The very high LOD score coupled with the significance of the D locus make the entire LG 18 a significant QTL (P<0.01) (black stars) (see Table S5).
