Figure 4From: Probable presence of an ubiquitous cryptic mitochondrial gene on the antisense strand of the cytochrome oxidase I geneContrasts in the numbers of AGR codons in the mitochondrial gau genes of primates. Analyses made between the lineages with and without antisense antitermination tRNA (from nodes A-N in Figure 3) as a function of the divergence times between these lineages. Numbers near data points refer to the smallest sample size used in the contrast calculation. Open symbols are for nodes where the antisense antitermination tRNA was presumably lost. Filled symbols indicate gains according to the parsimonious interpretations of Figure 3.Back to article page
