what was most likely true regarding the genetic mutations that occurred during the years mosquitoes were evolving resistance to ddt? group of answer choices the number and effect of mutations that occurred was not influenced by ddt. most of the mutations that occurred helped the mosquitoes survive. the number of mutations occurring in the population increased when ddt was first applied, and then decreased when the mosquitoes finished adapting. the mutations occurred because mosquitoes needed to survive.

Respuesta :

The number and effect of mutations in mosquitoes are not affected by DDT but are influenced by the genes of mosquitoes that are resistant to DTT.

DDT (Dichloro Diphenyl Trichloroethane) is a synthetic organic insecticide that was first discovered and used widely in 1945. DDT during World War II saved around 25 million lives, especially from the threat of malaria and typhus. However, in 1948, reports of DDT resistance in mosquitoes and flies began to be reported. In 1954 Anopheles sundaicus was declared resistant to DDT.

Some insects are resistant to DDT. Once DDT is discovered, insects that do not have innate resistance and are exposed to this chemical will be wiped out from the population. Over time, the previous few resistant insects multiplied. Eventually, the entire species became a population of DDT-resistant members. When this happens DDT becomes ineffective against that insect species.
