In snapdragons, a cross between red-flowered and white-flowered plants produces pink-flowered F1 plants. This is an example of:
Show answer and explanation
Correct answer: Incomplete dominance
Incomplete dominance occurs when the phenotype of the heterozygote is an intermediate blend of the two homozygotes. This is a deviation from Mendel's principle of complete dominance.
