Figure 4

Population structure of sprint and distance sled dogs during successive increase in assigned population numbers. The population structure of 84 unrelated Alaskan sled dogs of even distribution between four sprint and four distance kennels. The 42 Alaskan sled dogs from the sprint kennels are on the left side of the figure and the 42 Alaskan sled dogs from the distance kennels are on the right side of the figure. Each population is designated by a different color in the chart. Individuals are categorized based on the percentage of their allelic pattern belonging to each of the populations. Figures 4A-G show a successive increase in the assigned number of populations from K = 2 through K = 8. In total, eight sub-populations, four in sprint dogs and four in distance dogs, were documented from the sampled Alaskan sled dogs.
