Figure 3. Comparison between red color expression in fathers and the red sensitivity of their daughters (n = 25).

Relationship between daughters' relative sensitivity at 590 nm and fathers' (A) red chroma (after negative reciprocal transformation) and (B) chromaticity, respectively. The lines are the least square regressions [(A): Y = 0.413x+1.897, R ² = 0.547, F = 27.80, P<0.0001; (B): Y = 3.997x−0.211, R ² = 0.373, F = 13.70, P<0.01].
