FISH results with representative pictures of metaphase spreads (chromosomes stained with propidium iodide, probes labeled with fluorescein isothiocyanate, pictures taken separately, colorized and overlaid). The positions are indicated on a schematic representation of the W chromosome. The heterochromatic region of the chromosome is in dark red.
