From: Uncovering the evolutionary history of neo-XY sex chromosomes in the grasshopper Ronderosia bergii (Orthoptera, Melanoplinae) through satellite DNA analysis

Fig. 2

Neo-Y five chromosomes variants revealed by physical mapping of the two satDNAs exclusive of neo-Y chromosome, i.e. Rber248 (green) and Rber299 (red). Note in (a-c, e) that the Rber248 is maintained in the same position while the Rber299 is involved in the paracentric inversion, that involved distinct sizes of the neo-Y. In d note the enlargement of the neo-Y and that the Rber248 and Rber299 are maintained near each other, but in inverted order in comparison to the other neo-Y variants. The percentages indicate the proportion of individuals harboring the distinct variants of neo-Y in embryos (mitosis) and adults (meiosis)
