Genetic diversity in the mitochondrial DNA of the Iranian commomnatvie and exotic chicken breeds
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 1
Abstract
Genetic diversity which exists among animals has been created as a result of evolution process during so many years and considering different problems such as economic conditions and the time duration of performance of this program, first, genetic potential and similarities existing among different races should be examined. According to sensible characteristics of the native breeds of the animals existing in Iran and in order to maintain and save original and native animals, researches should be carried out. One of the indicators in determining genetic diversity in animals is the area of controlling of the gene of the mitochondrion. And in this research, using this indicator, the similarities and differences between native common chickens of Iran and some foreign exotic breeds of broiler and layer breeds of chickens determine and the genetic diversity among them estimated. In this research a number of 20 native common chickens were used among which there were 17 different specific haplotype with haplotype 13th including four samples of mentioned chickens. Achieved haplotype 13th with three sub-category of Jungle red chickens, two types of White Leghorn chickens, one type of New Hampshire red chickens and three different types of Asian-breed chickens (Tibetan, Silky, Laos) totally showed difference in80 gene place. The results of sequence analysis, the heliotype and nucleotide diversity were calculated 1and 0.163 respectively. Considering the phylogenetic graph among the created haplotypes.
