Fig. 4From: Reconstruction of avian ancestral karyotypes reveals differences in the evolutionary history of macro- and microchromosomesAssociation between the fraction of chromosome rearranged and evolutionary time for larger (AVI1–14 + Z) and smaller Avian ancestor chromosomes (AVI15–28). Blue and orange lines depict linear regressions for smaller and larger Avian ancestor chromosomes, respectivelyBack to article page
