dorcas gazelles Gazella do rcas ssp. sampled in AI Wabra all have karyotypes identical to the African representatives of dorcas gazelle (compare Figures 12.2 and 12.3). J IX II 11 I. :: •• At 01 II .t t 6* to .a .' " A' •• II xx Figure 12.4 Saudi gazelle Gazella saudiya. female D4 (2n=47). KKWRC. Reprinted from Rebholz " oZ. (1991). The submetacentric X-chromosomes of the Saudi gazelle (Figures 12.4 and 12.5) are double the size of the largest autosomes. probably caused by an X-autosome translocation. which is very common in gazelle. Autosome numbers of the seven Saudi gazelles studied vary between 45 and 50. which represents considerable variation within a species (Table 12.1). However. recently we discovered a female Saudi gazelle from AI Areen Wildlife Park with 51 autosomes (Kumamoto and Rebholz. unpublished data). which brings the range of autosomes between 45 and 51. Not only do autosome numbers vary between Saudi gazelles. their karyotypes also differ. Variation of metacentric chromosomes is very conspicuous. Their numbers vary between 10 and 13 and some seem to be single (see Figures 12.4 and 12.5). The other autosomal chromosomes are subtelocentric and their numbers vary from 32 to 39 (see Table 12.1). Some paired chromosomes do not seem to be homologous pairs (arrow in Figure 12.4). but this is difficult to prove in these unbanded karyotypes. Data from banded chromosome descriptions are not available yet. so it is not known which chromosomes are involved in translocations. More individuals of Saudi gazelle need sampling to study the extent of the variation in this species. 123

Transversions, transi tions and nucleotide position in the codon are not taken into account. The cytochrome b gene showed 1.0 to 1.2% base pair differences between Saudi dorcas gazelle and three dorcas gazelle from Africa, whereas the dorcas gazelle from Africa all differ by 1.6% from each other (Table 12.2). Even allowing for stochastic error, all dorcas gazelle subspecies are very closely related, since they differ 124
