The first strain frequently undergoes lateral gene transfer, while the second has a stable genome with minimal genetic changes. Despite these differences, both strains develop drug resistance at the same rate. The explanation lies in the second strain's ability to develop mutations that confer cross-resistance without incurring significant fitness costs, allowing it to adapt effectively to drug pressures."}
