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

<p>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): <i>Y</i> = 0.413x+1.897, <i>R</i>² = 0.547, <i>F</i> = 27.80, <i>P</i><0.0001; (B): <i>Y</i> = 3.997x−0.211, <i>R</i>² = 0.373, <i>F</i> = 13.70, <i>P</i><0.01].
