Figure 1. High-density linkage map and estimated recombination rates of the Nasonia genome.
High-density linkage map of the Nasonia parasitoid wasp genome inferred from segregation data of 1,255 markers in a N. vitripennis (♀)×N. giraulti (♂) F2 hybrid population of 112 male embryos. Horizontal bars (1.01–5.51) represent clusters of markers with no recombination among them (see Table S5). The average distance between the 1,255 markers and 265 marker clusters was 0.3 cM and 1.7 cM, respectively. The heat map next to the linkage map depicts the estimated local recombination rate (cM/Mb) in the corresponding region of parasitoid wasp genome. The local recombination rate was approximated for a total of 259 overlapping windows of two consecutive marker clusters each and an average width of 3.4 cM (Table S7).
