Seven genes drive snapdragon petal color shifts that determine pollination success
Wild snapdragons use seven genes to fine-tune their petal colors as visual signals to attract bees. Researchers found that these genetic variations produce subtle but meaningful differences in flower color. These color distinctions play a critical role in the survival of the plants, particularly in narrow hybrid zones. In these zones, flowers with less effective colors are less likely to be pollinated and therefore less likely to pass on their genes.
