Table 1.

SNP distribution patterns (SDP). Distribution of SNPs and alleles in total and per chromosomes I to X for each SDP. Strain names and place of isolation are give in the column headers. At SDP 14, O vs S shows those SNPs different between the two strains isolated from Orsay and the two strains isolated from Santeuil
