Emergence of a floral colour polymorphism by pollinator-mediated overdominance

Emergence of a floral colour polymorphism by pollinator-mediated overdominance

Examples of overdominance are usually explained by deleterious effects in homozygotes. Here, Kellenberger et al. describe a case of overdominance in the floral color of the Alpine orchid Gymnadenia rhellicani apparently maintained by pollinator preferences without deleterious effects in homozygotes.
