Comparative map of TRDL between and within species of M. guttatus. The linkage group is indicated above both intraspecific [g × g (M. guttatus × M. guttatus)] and interspecific [g × n (M. guttatus × M. nasutus)] maps. Hatch marks indicate marker placement. Only terminal markers and communal markers are labeled on each map, with dashed lines connecting communal markers. Linkage groups with a single communal markers are matched up arbitrarily; note the orientation could be rotated. Due to placement of additional codominant markers to the previously published interspecific map (Fishman et al. 2001), several AFLP markers were ousted to maintain basic mapping criteria. The following changes were made to the g × n map: LG2, addition of MgSTS56, slight separation of BA172 and CB280; LG6, addition of MgSTS25; LG9, addition of MgSTS35 and removal of BC108, slight separation of CA261 and CB115; LG10, addition of MgSTS43 and removal of AA153c and AA100; LG11, addition of MgSTS19 and MgSTS87, removal of BA387, change in map order for CYCA, AAT356, BD100, BB124, BA196, slight separation of BB124 and BA196; and LG14, addition of MgSTS18. Arrows point to locations of TRDL or detected regions of distortion. Solid arrows represent markers distorted toward excess IM (M. guttatus) alleles, open arrows represent markers distorted toward either excess DUN or M. nasutus alleles, stippled arrow represents distortion with an excess of heterozygotes, and shaded arrow represents distortion with a deficiency of heterozygotes.
