From: Characterization of the genetic pool of the Canadienne dairy cattle breed
Frequency of the five runs of homozygosity (ROH) length ranges (in Mb) in the six Canadienne purity groups, based on genome-wide analysis of 640K SNPs. Standard deviation is shown as error bars (low purity at the ROH range of 4–8 Mb contained a single individual). Letters indicate a significant difference among purity groups for each ROH range, based on Duncan’s test (P < 0.05). Darkest to lightest shade: original, fullblood, high purity, moderate purity, crossed, low purity
