Fig. 5From: Sex chromosome evolution in snakes inferred from divergence patterns of two gametologous genes and chromosome distribution of sex chromosome-linked repetitive sequencesFISH of three repetitive sequences in snakes. FITC-labeled E. quadrivirgata BamHI-4 repeat was hybridized to PI-stained metaphase spreads of B. constrictor (a), R. tigrinus (b), and B. arietans (c). E. quadrivirgata BglI-15 repeat was hybridized to metaphase spreads of R. tigrinus (d), P. flavoviridis (e), and B. arietans (f). The (AGAT)8 microsatellite motif was hybridized to metaphase spreads of E. quadrivirgata (g), R. tigrinus (h), and P. flavoviridis (i). Arrowheads indicate hybridization signals on sex chromosomesBack to article page
