On the basis of inheritance, mutations are somatic or inherited. Inherited or genetic mutations are those mutations that occur in germ cells. These cells are inherited by the offspring from their parents as they are present in gametes. All cells of a multicellular organisms are made up of a single cell zygote.
Anopheles is a genus of mosquito first described and named by J. W. Meigen in 1818. About 460 species are recognised; while over 100 can transmit human malaria, only 30–40 commonly transmit parasites of the genus Plasmodium, which cause malaria in humans in endemic areas.
