Question

select all that apply
for insect populations to become increasingly resistant to pesticides,

□ resistance must be genetic
□ resistance must have no effect on fitness
□ selection must occur
□ hardy - weinberg equilibrium must be present

need help? review these concept resources.

Explanation:

1. For insects to develop pesticide - resistance, the resistance trait must be genetic so it can be passed on to the next generation.
2. Selection occurs when pesticides kill non - resistant insects, leaving resistant ones to reproduce, increasing the frequency of the resistance allele in the population.
3. Resistance can have an effect on fitness in some cases, and Hardy - Weinberg equilibrium implies no evolution (including no development of resistance), so those two options are incorrect.

Answer:

resistance must be genetic, selection must occur
