Investigating polymorphism gene Aguti in Arabic horses of Khuzestan
Basic color in horses, such as black and white, brown and chestnut ASIP and MC1R gene is affected. The relationship between color horse and purity the study of gene polymorphism Aguti put special attention. The purpose of this study was to evaluate the polymorphism in exon 2 gene Aguti population of Arabic horse in Khuzestan. In this study, PCR-RFLP method for the detection of different alleles of the Aguti gene in horses used. Bleed extension of the 45 head of horses in the city of Ahvaz, Dezful and Shush were collected. Polymerase chain reaction 101 bp fragment of exon 2 gene and gene-specific primers were used Aguti. 11 bp deletion in exon 2 gene ASIP (Aguti signaling protein) occurred because of the In / del (delete and Insertion) of the gene Aguti. Finally three band pattern AA, Aa, aa abundance 0.414, 0.457, 0.127, respectively. The allele frequencies of A and a 0.644 and 0.356 respectively.The results showed that this fragment of gene polymorphism and genotype AA, Aa, aa population was established. The results showed that there is Hardy-Weinberg dis equilibrium in the studied population.
