In Mirabilis jalapa, there are two types of pure breeding plants, red flowered and white flowered. On crossing them the F1 plants or hybrids possess pink flowers. On selfing them, F2 generation has plants in the ratio of 1 red : 2 pink : 1 white flowered plants with phenotypic ratio being same as genotypic ratio.
