Figure 5From: Genetic diversity of canine olfactory receptorsRelationship between SNP and haplotype number. Distances between points were calculated with R software (maximum distances) [43] and used to cluster OR genes. With k = 4, a group of 5 OR genes (in light blue) with a large number of SNP but a small number of haplotypes was identified, together with a group of 11 OR genes (in green) with a large number of haplotypes and a small number of SNP. We excluded from this last group the 4 OR genes with only one SNP and 2 haplotypes. Note that an individual point may correspond to more than one OR gene.Back to article page
