Genetic map of the CAST/EiJ extended pseudoautosomal region (PAR). (A) Recombinant chromosomes in the extended PAR in the PWK/PhJ $\times$ CAST/EiJ cross. The expected nonrecombinant haplotype for sex is shown in gray and the recombinant haplotype in black. Blue bars show the interval between flanking markers (with points nudged to avoid overplotting). CAST/EiJ and canonical PAR boundaries are indicated by red dashed lines. Physical positions of markers from the 77K array are shown in the top panel. (B) Physical (left) and genetic (right) positions are shown for informative markers in the PWK/PhJ $\times$ CAST/EiJ and WSB/EiJ $\times$ CAST/EiJ crosses, pooling across both array platforms. Red diamond indicates boundary of canonical PAR.
