Fig. 3From: Evolution of bird sex chromosomes: a cytogenomic approach in Palaeognathae speciesFemale metaphase plates of the emu highlighting the chromosomal location of microsatellite repeats, indicated in the lower right corner in red. While the W chromosome was appropriately identified by a sequential hybridization with the microsatellite (GA)n, the Z chromosome could not be properly identified based on its morphology.
