Detailed explanation-1: -This is called as incomplete dominance. For example, flower colour in Mirabilis jalapa (Snapdragon). The red flower is the dominant character and the white flower is recessive character. There is blending of the two alleles.

Detailed explanation-2: -Snapdragon also shows incomplete dominance by producing pink-colored snapdragon flowers. The cross-pollination between red and white snapdragons leads to pink color flowers because none of the alleles (white and red) is dominant.

Detailed explanation-3: -Figure 21: A cross between a red and white snapdragon will yield 100% pink offspring. This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time.

Detailed explanation-4: -When a red-flowered plant is crossed with a white-flowered plant, the F1 generation has pink flowers.

Detailed explanation-5: -In the case of snapdragons, the red flower color is dominant to white, but the presence of both alleles results in a blending of the two, which leads to a pink appearance of the flowers.
