Whatever the pest in question, the evolution of pesticide resistance (i)____ the Darwinian algorithm.

Too early to cast a preview of the first blank. Will see what the sentence ahead tells us


Random genetic variations arise all the time in a population, especially among fast breeders.

random variations arise every time since. Ok

Most of those variations are either of little consequence or are decidedly inadvisable, and they are accordingly (ii)_____ selective pressures, or are quickly swept from the gene pool.


However, those variation that come up a negligible, basically. And if so, the are ignored by species. Notice also to support this bloank by the end of the sentence quickly swept from the gene pool.


Every so often, however, a mutation of enormous utility like toxin resistance springs up, and the novel trait soon becomes (iii)______.

Hopwevre, time to time the species develop pesticides resistance . Therefore, they incorporate it in their genes. The consequence is that this resistance becomes the normality. The third blank is I.

As it turns out, the first blank from the overall meaning of the sentence is conforms to because the real gist of the problem is that the resistance is incorporated over time.
