Introgression and persistence of cultivar alleles in wild carrot (Daucus carota) populations in the United States.

Abstract excerpt

PREMISE: Cultivated species and their wild relatives often hybridize in the wild, and the hybrids can survive and reproduce in some environments. However, it is unclear whether cultivar alleles are permanently incorporated into the wild genomes or whether they are purged by natural selection. This question is key to accurately assessing the risk of escape and spread of cultivar genes into wild populations....
