- Crossing two living things with recessive traits causes their offspring to have that recessive trait
- White flower is a recessive trait in snapdragon plant
- Hence, crossing two snapdragon plants with white flower will cause the offspring to have white flowers

So, crossing two snapdragon plants with white flower will cause the offspring to have white flowers
Question
In snapdragon plants, red flowers are dominant to white flowers. When red-flowered plants are crossed with white-flowered plants, pink flowers are produced. If a researcher wants to produce plants with only white flowers, what color should the parent plants be?
