Schematic representation of diagnostic field characteristics of giant sable antelopes, roan antelopes and their F1 hybrids and backcrosses observed in Cangandala National park, Angola.
Drawings are based on photographs taken during camera trapping and animal capture sessions carried out in 2009–2011. The hybrids and backcrosses represented were confirmed through genetic analysis. The sable x roan hybrids (robles) are phenotypically intermediate between the parental species, while the hybrids x roan backcrosses have features more closely resembling roan. The female backcross shows the abnormal horns observed in a single individual.
