Analysis of gene content of the microdissected chromosomes. Z1 chromosome of F. pardalis, and Z and W chromosomes of F. oustaleti are enriched in genes with homologs linked to several chicken chromosomes, particularly 1, 4, 25, 33 and Z (a). The vast majority of these genes are probably pseudoautosomal, 42 genes with homologs linked mainly to chicken chromosome 4 could be Z-specific, because they were detected in both Z chromosome of F. oustaleti and Z1 chromosome of F. pardalis, but not in the sequence of the microdissected W chromosome (b). Outer numbers correspond to chicken chromosomes, inner numbers to number of genes (b). All data are included in Table S2.
