FIGURE 3.

Associations between the OXTR SNPs and the behavior score in the Greeting during separation. The dogs were divided into two groups based on the behavior during separation. In the case of dogs, which did not show stress signals during separation, (A) dogs carrying the A allele in the -213A/G SNP greeted the experimenter more than dogs carrying the GG genotype, and (B) dogs carrying the C allele in the rs8679682 SNP greeted the experimenter more than dogs with a TT genotype. In the case of dogs, which showed stress signals during separation, (C) females carrying CC genotype in the -94T/C SNP greeted the experimenter more than the CT and TT genotypes, while the relation was the opposite in males; (D) females carrying the GG genotype in the -74C/G SNP received higher scores than those carrying the CC genotype, while the relation was the opposite in males.
