Responses A Sexual reproduction must occur.Sexual reproduction must occur. B The final population is purely random.The final population is purely random. C Genetic variation must exist in the population.Genetic variation must exist in the population. D Those with the highest pesticide resistance reproduced.Those with the highest pesticide resistance reproduced. E Only those with the highest pesticide resistance level survived exposure to the pesticide.
