Final answer:

Incomplete dominance in snapdragons explains the blending of flower colors where red and white snapdragons produce pink offspring.


Explanation:

Incomplete dominance is observed when a cross between red snapdragons and white snapdragons results in pink flowers in the offspring. In this case, neither allele for flower color is completely dominant over the other; both are expressed simultaneously, leading to the intermediate pink color.

An example provided with snapdragons demonstrates how the genotypic and phenotypic ratios are derived from crossings with incomplete dominance, showcasing the blending of traits in the heterozygous offspring.

This phenomenon occurs because the red allele's pigment is diluted in the heterozygote, creating the pink color due to the white background of the flower petals.
