Fig. 2From: Global sequence diversity of the lactate dehydrogenase gene in Plasmodium falciparumd N –d S plot of the gene encoding lactate dehydrogenase of P. falciparum. Sequences used in the analysis corresponded to nucleotide positions 31–948 with respect to P. falciparum reference strain 3D7. The d N –d S values of zero, equivalent to a d N /d S ratio of 1, indicate neutral selection on the geneBack to article page
