Surveying the structure and genetic diversity of red foxes in the North East of Iran, based on cytochrome b gene

To study the genetic structure of red foxes in North East of Iran, 25 tissue samples were collected from three provinces (Razavi Khorasan, North Khorasan and Golestan). After DNA extraction, mitochondrial cyt-b gene was amplified by primers using polymerase chain reaction (PCR); then 1098 base pairs of this gene were edited for each sample after purification and sequencing processes. Then by analyzing of this partial sequence of the samples: polymorphism sites, nucleotide and haplotype diversity, the amount of genetic differentiation (using Fst index), Demographic history (using Harpending's raggedness index, Tajima and Fu Fs test) were calculated and phylogenetic tree and haplotype network were drawn by Baysian and Median joining logic in order. The results showed that there were 13 different haplotypes and 22 polymorphic sites between the samples and haplotype diversity was equal to 0.88. Fst (P
