Figure 4From: Next-generation pyrosequencing of gonad transcriptomes in the polyploid lake sturgeon (Acipenser fulvescens): the relative merits of normalization and rarefaction in gene discoveryFrequency plot of Ts/Tv ratios for 60 contigs with a significant BLAST hit. Points represent the number of contigs with that specific Ts/Tv ratio. Ts/Tv ratios greater than 1 indicate an excess of transitions, those lower than 1 indicate an excess of transversions. A line of best fit is plotted through the data.Back to article page
