Non-pollinator selection for a floral homeotic mutant conferring loss of nectar reward in Aquilegia coerulea.

Abstract excerpt

Here, we describe a polymorphic population of Aquilegia coerulea with a naturally occurring floral homeotic mutant, A. coerulea var. daileyae, where the characteristic petals with nectar spurs are replaced with a second set of sepals. Although it would be expected that this loss of pollinator reward would be disadvantageous to the mutant, we find that it has reached relatively high frequency (∼25%) and is under...
