Figure 2

Standard curves for converting the intensity of discriminating peaks into frequency of corresponding markers. Standard curves were established for all 14 discriminating-peaks shown in Figure 1. Only those for VIT2.1 and VIT 4.2 are shown here, as they illustrate the worst and the best fit, respectively, between the recorded data and the polynomial regression function calculated using Excel (correlation coefficients R², are shown). Vertical bars represent standard deviation among repeats.
