“…However, the haplotypes of five other mouflons cluster with an urial haplotype, suggesting gene flow from urial into the Asiatic mouflon population in Iran [17]. Previous field and genetic evidence have shown the presence of hybrids between urial and Asiatic mouflon in this country [29,30]. Inter-species introgressions have also been detected in several genera [31], including the wild and domestic sheep species [13,32].…”

“…Accordingly, mouf lon/urial hybrid zones with individuals displaying intermediate chromosome numbers of 55 to 57 are observed in northern (Nadler et al 1971) and southeastern Iran (Valdez et al 1978). These data have been interpreted in support of a single 'mouf loniform' (O. orientalis) species, comprising mouf lon and urial populations (Valdez et al 1978;Valdez 1982). The International Union for the Conservation of Nature and Natural Resources (IUCN) has essentially adopted this classification of only three species (O. orientalis, O. ammon and O. nivicola) of Eurasian wild sheep (Shackleton et al 1997).…”

“…Geist (1991a) recognizes six species for the genus Ovis: the primitive vignei, the paedomorphic orientalis, the hypermorphic ammon and three pachycerine species, nivicola, dalli and canadensis. Despite the differences in chromosome number, different species of the genus Ovis can hybridize in captivity (Vorontsov et al 1972;Nadler et al 1973b) and natural habitats where ranges overlap (Nadler et al 1971;Valdez et al 1978), and produce fertile offspring. Accordingly, mouf lon/urial hybrid zones with individuals displaying intermediate chromosome numbers of 55 to 57 are observed in northern (Nadler et al 1971) and southeastern Iran (Valdez et al 1978).…”

Complete mitochondrial DNA (mtDNA) control regions (CR) were sequenced and analysed in order to investigate wild sheep taxonomy and the origin of domestic sheep (Ovis aries). The dataset for phylogenetic analyses includes 63 unique CR sequences from wild sheep of the mouflon (O. musimon, O. orientalis), urial (O. vignei), argali (O. ammon) and bighorn (O. canadensis) groups, and from domestic sheep of Asia, Europe and New Zealand. Domestic sheep occurred in two clearly separated branches with mouflon (O. musimon) mixed into one of the domestic sheep clusters. Genetic distances and molecular datings based on O. canadensis CR and mtDNA protein-coding sequences provide strong evidence for domestications from two mouflon subspecies. Other wild sheep sequences are in two additional well-separated branches. Ovis ammon collium and O. ammon nigrimontana are joined with a specimen from the transkaspian Ust-Urt plateau currently named O. vignei arkal. Ovis ammon ammon, O. ammon darwini and O. vignei bochariensis represent a separate clade and the earliest divergence from the mouflon group. Therefore, O. musimon, O. vignei bochariensis and Ust-Urt sheep are not members of a 'moufloniform' or O. orientalis species, but belong to different clades. Furthermore, Ust-Urt sheep could be a hybrid population or an O. ammon subspecies closely related to O. ammon nigrimontana.

“…In addition, two main wild sheep species, Asian mouflons ( Ovis orientalis ) and the smaller type Asiatic urial ( Ovis vignei ), are found in protected natural areas and national parks in Iran (Valdez et al . ). Generally, all Iranian sheep breeds are mainly used for mutton, but the Makui, Kalakui and Naini breeds are also considered excellent resources for wool production.…”

Multilocus genotypic data reveal high genetic diversity and low population genetic structure of Iranian indigenous sheep

Iranian livestock diversity is still largely unexplored, in spite of the interest in the populations historically reared in this country located near the Fertile Crescent, a major livestock domestication centre. In this investigation, the genetic diversity and differentiation of 10 Iranian indigenous fat-tailed sheep breeds were investigated using 18 microsatellite markers. Iranian breeds were found to host a high level of diversity. This conclusion is substantiated by the large number of alleles observed across loci (average 13.83, range 7-22) and by the high within-breed expected heterozygosity (average 0.75, range 0.72-0.76). Iranian sheep have a low level of genetic differentiation, as indicated by the analysis of molecular variance, which allocated a very small proportion (1.67%) of total variation to the between-population component, and by the small fixation index (FST = 0.02). Both Bayesian clustering and principal coordinates analysis revealed the absence of a detectable genetic structure. Also, no isolation by distance was observed through comparison of genetic and geographical distances. In spite of high within-breed variation, signatures of inbreeding were detected by the FIS indices, which were positive in all and statistically significant in three breeds. Possible factors explaining the patterns observed, such as considerable gene flow and inbreeding probably due to anthropogenic activities in the light of population management and conservation programmes, are discussed.
