From: Chromosomal evolution in Raphicerus antelope suggests divergent X chromosomes may drive speciation through females, rather than males, contrary to Haldane's rule

Figure 5

Effects of asymmetric pairing of heterochromatic (hc) blocks on meiotic progression in the homogametic sex. (a) Fully developed synaptonemal complex characterizing meiosis in RCA females (which possess no intercalary heterochromatin); (b–d) synapsis of heteromorphic Raphicerus X chromosomes, a potential outcome following interspecies hybridization showing large unsynapsed hc loops that would elicit an MSUC response in female meiosis. Red = PARs; Pink = euchromatic sequences orthologous to BTA Xp; Blue = euchromatic sequences orthologous to BTA Xq (Supplementary Fig. S2 for details).
