Detailed explanation-1: -Given that the snapdragons show incomplete dominance for this trait, we can assume that when they have this heterozygous genotype that their flower color will be a blend between white and red, which is pink flowers.

Detailed explanation-2: -In snapdragons, red flower color is incompletely dominant over the white-flowered plant, the heterozygous plants have pink flowers.

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: -In snapdragon i.e. Antirrhinum majus, the flower color is controlled by incomplete dominance. The snapdragon flower has two flower colours, red (RR) and white (rr). When cross-pollination occurs between red and white flowers, a pink (Rr) snapdragon flower is produced.

Detailed explanation-5: -The genotype for the pink flower is Rr and the genotype for the white flower is rr. This would lead to a 50% chance of the offspring having a phenotype of pink. 3.
