Figure 1.

Sample map of grey wolf populations sequenced and schematic of insulin-like growth factor 1 (IGF1) molecular markers and exons. (a) The numbers outside the parentheses are sample sizes for the long sequence (6331 bps) and the numbers inside are sample sizes for the short sequence (4881 bps). (b) The chromosomal segment on the bottom shows the location of 94 dog-derived single nucleotide polymorphism (SNP) loci shown as black vertical lines. The chromosomal segments on the top show the locations of SNPs and indels discovered from sequencing.
