Final answer:
Snapdragon flower color is an example of incomplete dominance, a genetic pattern where the heterozygous phenotype is a mix of the two homozygous phenotypes, resulting in pink flowers from red and white parents.
Step-by-step explanation:
The color of flowers in snapdragons is an example of incomplete dominance. This is a pattern of inheritance where neither allele is completely dominant over the other. As a result, the heterozygous phenotype is a blend of the two homozygous phenotypes. For snapdragons, this means that when a red-flowered plant is crossed with a white-flowered one, the resulting offspring have pink flowers, clearly demonstrating incomplete dominance.
