Genes 1 and 2 are shown as a pair of genotypes of dedicator of cytokinesis 7 (Dock7) gene and leptin receptor (Lepr) gene. M: wild type of Dock7; m: a mutation type (misty) of Dock7; +: wild type of Lepr; db: a mutation type of Lepr. The number of mice diagnosed is described. The mice examined from the company A and company B were 12 and 20, respectively. The number in parentheses denotes the percentage.
