Two- and three-color FISH mapping of DAPI-stained chromosomes of a male T. muenninki. FITC-avidin (green)– and rhodamine-DIG (red)–labeled BAC DNA probes were used. Scale bar indicates 10 μm. Arrowheads indicate the locations of each BAC clone. Eleven genes, GEMIN4 and FOXK2 (a), DOC2B and UTS2R (b), PRPF8 and ACTG1 (c), SSTR5 and NDE1 (d), EMP2, LMF1, and MYH11 (e, f) were mapped on T. muenninki neo-sex chromosomes. (g) Comparative cytogenetic maps from short arms of T. muenninki sex chromosomes (TMU Xp and Yp), mouse chromosome 11 (MMU 11), and rat chromosome 10 (RNO 10). The locations and order of the genes are shown on the side of each chromosome. The location of genes with asterisk and ideograms of T. muenninki neo-sex chromosomes were taken from Murata et al. (2012). The gene order and ideogram of MMU 11 and RNO 10 was taken from the NCBI database (http://0-www-ncbi-nlm-nih-gov.brum.beds.ac.uk/)
