A mutation occurs in a mosquito. As a result, some of the mosquitos offspring are a resistant to a chemical used to kill mosquitoes. They survive when the chemical is sprayed. Explain why the mosquitos offspring has resistance to the chemical and whether the effect of the mutation is beneficial, neutral, or harmful to the mosquitos.

Natural selection can be defined as the process by which individuals that exhibit certain phenotypic traits in a given environment have more chances to survive and reproduce. Mutations are random genetic changes produced during the replication of DNA. In general, mutations have a negative effect, but there are situations where mutations confer an adaptive advantage. Natural selection, which is a nor random process, favors mutations that give an adaptive advantage. In this case, resistant mutant mosquitoes are able to survive and reproduce, thereby these mutations will pass on to their offspring.

Mosquitoes' offspring are resistant to a chemical used to kill mosquitoes due to the mutation called adaptive resistance that occurs due to adaptive radiation which is beneficial to the mosquitoes.

Adaptive mutation

Adaptive resistance takes place by changing DNA due to a long time tolerance to a chemical, antibiotic, or insecticide. In this case, mosquitoes develop resistance to the chemical by changing their DNA.

Mutation can be neutral, beneficial, or harmful. Most of the cases are neutral, however in this case this mutation is beneficial to the mosquitoes.
