Figure 4From: Phylogenetic patterns of emergence of new genes support a model of frequent de novoevolutionCircos plots of chromosomes and phylogenetic age of their genes. Clockwise orientation, tick marks every 10 Mb. Genes become younger towards the outer part of the circle (represented by hues of red to blue). A. Whole genome representation. B. Chromosome 14. Green mark indicates a local cluster of young genes spanning several phylostrata.Back to article page
