Abstract:

Abstract 10.1002/zoo.1430100607.abs Karyotypes of Saudi gazelle (2n = 47 female, 2n = 50/51 male) are presented for the first time. The three karyotypes shown here vary in the numbers of metacentric chromosomes, but the cause of this variation is not yet known. Although Saudi gazelle are often regarded as a subspecies of Dorcas gazelle, the chromosome numbers and karyotypes of Saudi gazelle are too different from Dorcas gazelle (2n = 30 female, 2n = 31 male) for them to be considered a subspecies. It is also unlikely that these species would interbreed. In view of the present findings, the taxonomic status of this highly endangered gazelle needs to be resolved as soon as possible.
