Comparative mapping between chicken chromosome 21 (GGA21) sequence map and duck chromosome 22 (APL22) radiation hybrid maps. Left and right: position of duck scaffold markers on the chicken genome. Middle left: RH map built with the Carthagene software. Middle right: RH map built with the comparative approach, followed by statistical confidence measures for genome maps. Framework markers for the CarthageneRH map and robust markers for the ComparativeRH map are in red.
