When One's Not Enough: Colony Pool-Seq Outperforms Individual-Based Methods for Assessing Introgression in .

The human management of honey bees () has resulted in the widespread introduction of subspecies outside of their native ranges. One well known example of this is , native to Northern Europe, which has now been significantly introgressed by the introduction of C lineage honey bees. Introgression has consequences for species in terms of future adaptive potential and long-term viability.
