Figure 3From: The molecular basis of color vision in colorful fish: Four Long Wave-Sensitive (LWS) opsins in guppies (Poecilia reticulata) are defined by amino acid substitutions at key functional sitesQuantitative PCR amplification plot and logarithm histogram of original copy number. Four LWS transcripts from the cDNA of three adult guppies were quantified using qPCR with the amplification plot shown. Ct (dR) values are given in Table 2. A histogram showing the averaged logarithm value of original transcript copy number is shown (with standard error bars included).Back to article page
