NEET BIOLOGY

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: -The basis for the intermediate color in the heterozygote is simply that the pigment produced by the red allele (anthocyanin) is diluted in the heterozygote and therefore appears pink because of the white background of the flower petals. Figure 22: The results of crossing two pink snapdragons.

Detailed explanation-3: -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-4: -Note: The Snapdragon flower shows incomplete dominance in them. In the heterozygous flowers, they are unable to show the red color (dominant) and neither white color (recessive) is able to express itself fully. In such a condition a pink flower is born which shows only some part of both the color.

Detailed explanation-5: -In snapdragons, red flower color is incompletely dominant over the white-flowered plant, the heterozygous plants have pink flowers.
