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

Figure 4

The morphology of the X chromosome differs among the Raphicerus species. All three show the presence of the so-called “acrocentric caprine X” (also referred to as the Suni type) with sequences orthologous to BTA Xp transposed approximately two thirds down the length of the euchromatic X chromosome43. (a) Schematic showing the relative positions of the BTA Xp (green) and BTA Xq (red) sequences and (b) FISH results using microdissected painting probes to this region. The distal heterochromatic block in RSH Xq was located between BACs 198N19 and 311B9. BAC 23A23 was proximal to 198N19. Key: * = satI DNA; O = SINE/LINE DNA repeats; */O = RME Xp arm comprises both satI and SINE/LINE; PAR = pseudoautosomal regions.
