Description One of the main tasks of the PROCAMED project is to promote research on genetics of dromedary camel. In
this regard, and to evaluate the genetic diversity among Tunisian dromedary camel, a total of 62 blood samples
were collected from unrelated animals in three different regions (Tataouine, Medenine and Kebili) and
belonging to three sub-populations (Ourdhaoui Médenine, Ourdhaoui Tataouine and Merzougui) defined on the
basis of morphologic and geographic criterions. From seven microsatellite markers used only four were
successfully amplified resulting in a total of 26 alleles observed in the three sub-populations with a mean
number of alleles (MNA) of 6.5. Unbiased expected heterozygosity (He) ranged from 0.76 to 0.84 whereas the
observed heterozygosity was absolute (Ho = 1) and an excess of heterozygotes was observed in the three groups
for all four loci. The mean estimates of the fixation index FST was 0.052 showing a moderate genetic structure
between the different sub-populations. Little differentiation was observed between Ourdhaoui Médenine and
Merzougui sub-populations, compared to Ourdhaoui Tataouine sub-population which seems to be more
established. The results showed the limits of camel classification on the basis of only morphologic and regional
distribution criterions.
