Genetic diversity and population structure of old world camelids (camelus dromedaries and camelus bactrianus) in iran using mitochondrial dna

Abstract

This study was conducted to investigate the genetic diversity of Iranian camels using mitochondrial DNA. A fragment of 1052 bp cyt-b was amplified and sequenced in 120 individuals from four camel populations. The results revealed that there are 30 mutations for Bactrian camels and 9 mutations for dromedaries that lead to nine and six mtDNA haplotypes, respectively. Nucleotide diversity was calculated as 0.0015 and 0.0121 for dromedaries and Bactrian camel populations respectively. We found high haplotype diversity in Bactrian camel populations (0.886±0.145) and low genetic differentiation among dromedary populations. Phylogeny analysis showed different cluster for camelids.
