The number of distinct dog chromosomes syntenic to each scaffold, as predicted with two complementary methods: genome-scale alignment to identify syntenic dog chromosome(s) for each scaffold [12], and the number of dog chromosomes syntenic to each scaffold as identified by RACA. Circle diameter is proportional to the number of scaffolds, which is presented inside of or beside the circle. Green indicates that the same number of syntenic chromosomes was predicted by both methods; yellow that the methods predicted different numbers; and red that the scaffolds were excluded from the RACA assembly. Unlike the prior analysis, RACA did not compare the scaffolds to the dog Y-chromosome.
