Which two geographical locations are associated with the modern intentional introduction of the long-haired gene into the St. Bernard?
Answer
England and the United States
The initial lineage maintained by the monks favored the short coat for practical reasons. However, a historical divergence occurred later when breeders operating outside the hospice environment made conscious decisions to diversify the gene pool. Specifically, breeders in England and the United States intentionally introduced dogs possessing the long-haired gene into the existing lineage. This breeding modification resulted in the two distinct coat varieties—short-haired and long-haired—that are recognized today, marking a shift from the monks' original practical breeding focus.
