Drosophila At Room Temperature Essay

Decent Essays
The purpose of this experiment was to observe the life cycle process of Drosophila at room temperature (19-22 ˚C) and a cultured temperature at 27 ˚C. These temperatures were used as measurements to determine how rapidly reproduction occurred after one week.
Reproduction is a result of fertilization which leads to cleavage of cells. Time elapsed regarding reproduction varies from species to species. Particularly for this experiment is Drosophila. Drosophila is a fruit fly that has a shorter reproduction rate compared to other species. On average it takes these fruit flies nine days to hatch and become a fully formed adult. Prior to reproduction is the mating technique which occurs based off a series of motions and noises. Males which appear to have dark abdominal pigmentation display mating behavior consisting of orienting, tapping, singing followed by licking.

The larva stages are relevant for the rapid growth the larva undergoes as well as storage of energy. Binge eating leads up to the pupa stage. “These larval fat cells are refractive to autophagic cell death that removes most of the larval cells during metamorphosis.”( Aguil, JR) As the larva transitions the cells transition to a more mature specimen, the pupa. Within the pupa stage, the formation of the eyes and other segments such as legs and arms are formed. The body segment from pupa take a total of five days to complete.
A determining factor for how rapid the life cycle of Drosophila’s occurs is the environment. The first hypothesis for this experiment was, it is expected for the parents placed in the vials to die in increased temperature after one week. Also it was expected a new generation would be present in both vials after one week with the expectation of the progeny in the early larvae stage. The final hypothesis was there won’t be too much of a difference in the vials simply because the temperature difference was not
