Final answer:
The 'refuge' strategy proposed by Tabashnik relies on the survival of both Bt-susceptible and Bt-resistant pests to slow the evolution of Bt-resistance.
Step-by-step explanation:
The 'refuge' strategy proposed by Tabashnik to slow the evolution of Bt-resistance relies on C. the survival of both Bt-susceptible and Bt-resistant pests. This strategy involves planting a small area of crop that does not express the Bt toxin, which allows for the survival of Bt-susceptible pests. By creating a refuge for susceptible pests, they can interbreed with Bt-resistant pests, which reduces the chances of resistance evolving in the population. Over time, this can slow down the evolution of Bt-resistance.
