Dog genome analysis (IMAGE) University of California - Berkeley Caption Using ASCEND, UC Berkeley researchers determined the intensity and timing of founder events in 40 breeds of dogs. The most intense, with the greatest inbreeding, are labeled purple at upper right, with less intense founder events moving clockwise. African village dogs are the least inbred. The inner (gray) rim represents the founder age (in generations before present), with the bar height proportional to the founder age. The width of the bars is inversely proportional to the number of breeds within each role category.
