A heuristic search in the likelihood landscape revealed more complex likelihood profiles for data sampled in two-dimensional space relative to a linear transect. Randomized resampling of localities showed that deletion of sites away from the zone center can decrease cline width estimates whereas deletion of sites close to the center can significantly increase the width estimates. The results suggest that the geographic sampling design is very important in hybrid zone studies. The comparison of the two transects indicates cline widths are narrower for loci in the central part of the X chromosome, suggesting selection is stronger in this region and genetic incompatibilities may have at least partly common architecture in the house mouse hybrid zone.
