(a) Male- and female-specific autosomal recombination linkage map of great reed warbler (based on 43 microsatellite markers). Male maps are to the left in each linkage group. (b) Male-specific Z-chromosome linkage group (based on three microsatellite and four chicken-derived markers; see ). Note that the location of G61 is preliminary (see ). Locus positions are given by their distance in cM.
