A recessive marker gene for white flower was used to estimate the distance alfalfa pollinating insects would carry viable pollen. The amount of contaminate pollen disseminated by bees was a function of the bee species, distance, and season. The leaf-cutter bee did not carry pollen away from the base plot as far as the honeybee did. Endemic pollinators carried viable pollen as far as one mile.
