Detailed explanation-1: -A red snapdragon flower is crossed with a white snapdragon flower, and all the resulting flowers from the cross are pink.

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: -The Rr genotype shows the phenotype of pink flowers and the rr genotypic character shows the phenotype of white flower. This means that all the plants which are present as the progeny have the genotype as Rr. Therefore % of Genotype Rr is 100% here. The % of Phenotype is 100% for pink flowers in the progeny.

Detailed explanation-5: -when a cross is made between pink flower and red flower snap dragon plants, what proportion phenotype in the F 1 offspring could be expected to be red? In Snapdragon F1 progeny shows pink coloured flowers when a cross in made between red flowered and white flowered plants.
