A newly discovered strain of anopheles gambiae, a mosquito, is found to be resistant to a particular insecticide due to a new allele at a specific locus. When individuals of this strain are mated with individuals of an insecticide-susceptible strain of a. Gambiae, all offspring are susceptible. If males and females of these susceptible offspring are then mated with one another, what proportion of offspring do you expect will be resistant?.

weathering is the answer.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
