Phylogenetic relationships and genetic variation between two Iranian sheep breeds were analyzed using cytochrome b (cyt-b) gene sequences. The genomic DNA was isolated by salting out method and amplified cytochrome b gene using polymerase chain reaction restriction (PCR) method with a pair of primer. A partial sequence of cyt-b gene of Iranian sheep is 780 bp and contained 13 variable sites and 11 haplotypes. Phylogenetic analysis of haplotype in the combination with the sheep from GenBank showed that Iranian sheep made a separated cluster. This study is provided useful information for understanding relationships between breeds from different parts of the world. This study may simplify the future researchers and breeders for better understanding the genetic structure and breed differentiation for designing future breeding strategies to the conservation of animal genetic resources.

The genetic diversity and phylogenetic structure was analyzed in Marghoz goat population by mitochondrial DNA sequences. Phylogenetic analysis was carried out using hyper variable region 1 (968 bp) obtained form 40 animals. Marghoz goat proved to be extremely diverse (average haplotype diversity of 0.999) and the nucleotide diversity values 0.022. A total of 40 Marghoz goats were grouped into six haplotypes and the large majority of haplotypes were present in 15 animals. All Marghoz haplotypes were classified into C haplogroup and revealed remarkably high genetic distances within the population when compared with other Asian goat populations, indicating high genetic variation in the Marghoz goat. These results indicate high-divergence status of the Marghoz goat and will influence breeding and conservation strategies adopted for this breed.
