Since there is a color that dominants over another color, the red color should take the capital letter R and the white color should take the small letter r. Therefore, the heterozygous individual is symboled Rr. If crossing happened between Rr * Rr, the result will be both red flowered and white flowered with the ratio 3 red:1 white.
