Repetitive Sequence and Sex Chromosome Evolution in Vertebrates
Figure 1
C-banding in Australian dragon lizards showing accumulation of heterochromatin on W chromosome: (a) Ctenophorus fordi, (b) Pogona vitticeps. Note that the ZW sex chromosomes between these two species are nonhomologous [12], yet the heterochromatin accumulation on the W chromosomes is very similar. For more images see [42, 43]. Arrows indicate W chromosomes. Scale bars represent 10 μM.
