              Abstract
              
                              
                              
                              The present study was carried out to reveal 
                              haplotype and phylogenetic analysis of OLR1 gene 
                              in Jaffarabadi and Surti breeds of buffalo. Twenty 
                              nucleotide sequences generated from our previous 
                              study (Shabir, 2009) were used to reveal the 
                              haplotypes in OLR1 (Intron I) gene in the 
                              population of Jaffarabadi and Surti buffalo. Four 
                              haplotypes viz. H1 (CTA), H2 (TCT), H3 (CTT) and 
                              H4 (TTT) were observed with frequencies of 0.05, 
                              0.1, 0.15 and 0.7 respectively in the population 
                              studied. Phylogenetic analysis of these twenty 
                              sequences with the same region of Bos taurus 
                              distributed the sequences into four clusters based 
                              on the homology between them. Cluster I contained 
                              two sequences ( jb3 and jb8) bearing a common SNP 
                              at nucleotide position 843. Cluster III contained 
                              s3, s4 and s7 since they possessed a common SNP at 
                              nucleotide position 423, however s3 remained as an 
                              out group in this cluster since it contained an 
                              additional SNP at position 866. The remaining 
                              sequences had highest homology and fell in cluster 
                              II while as the sequence of Bos taurus remained as 
                              an out group on account of the difference in bases 
                              at many loci.
                              
                              
              
                              
              Keywords: Phylogenetics, 
                              haplotypes, OLR1 and Bubalus bubalis.
