Drosophila melanogaster

species known as Drosophila melanogaster was used to help demonstrate heredity with each set of flies possessing a different mutation from the wild type. D. melanogaster are often…

Drosophila melanogaster are often used as a model organism in laboratories due to the many advantages that the organism provides: short generation time, sexual dimorphisms, cost effectiveness and easiness to maintain, amongst others. The generation time of Drosophila is around 9 – 11 days, and phenotypes in men, such as sex combs, heavily pigmented abdomen, and shape of abdomen and size, makes of Drosophila melanogaster an effective organism to study. In Drosophila melanogaster, the males do…

Drosophila melanogaster, a species of common fruit flies, is widely used for biological research in studies amongst geneticists around the world. For many different reasons, these miniature organisms have become a favorite model organism for geneticists, biologists, physiologists, and many other scientists today, the obvious ones being their low cost, easy maintenance, ten-day generation time, and the fact that they produce large quantities of progeny. Besides these reasons, this species has…

Drosophila melanogaster is a group of flies normally known as a common fruit fly, and widely used as an experimental organisms because they possess the ability to breed rapidly, survive in laboratory controlled conditions and have observable genetic mutations that enables different phenotypic differences. Dihybrid crosses shows lineages of two observable characteristics in a species, it was found by Gregor Mendel. This allowed scientists to conclude that genetic information can be inherited…

Introduction Fruit fly Drosophila melanogaster that is used as a model to study genetics for more than a hundred years. Thomas Hunt Morgan, in the early 1900’s, used the heritable traits of a common species of fruit fly to develop our understanding of genetics. Morgan was the first to show through experiments that genes were located on chromosomes. He also found that certain fruit fly traits like eye color are found on the same chromosomes that also determine their sex. Fruit flies have several…

Introduction Drosophila melanogaster can be considered model organisms for the study of genetics. Some characteristics that contribute to this status are their quick lifecycles, large amount of offspring, and the presence of only four chromosomes. Drosophila melanogaster contain bristles on the thorax, head, legs, and abdomen. These bristles are used as a sensory mechanism, allowing fruit flies to detect their surroundings as they fly and walk around their environment (Yehuda, 2011). The rate…

Fruit flies (Drosophila Melanogaster – Figure 1) have been a model system for research on all levels of biology. Their small size, relatively cheap pricing, and short lifespans make them easy to care for and breed. More importantly, the fruit fly genome is completely sequenced, with 77% of searched human genetic disease genes matching 548 unique drosophila gene sequences (Reiter et al., 2001). This relationship between the genome of fruit flies and that of humans ensures fruit flies are…

Examining the inheritance patterns of genes of Drosophila melanogaster controlling some traits of eye color, body color, and wing shape by analyzing dihybrid crosses Csilla SzepeIntroduction Our report will describe the experiment of three dihybrid crosses where we would like to understand if certain traits of Drosophila melanogaster follow the pattern of autosomal, unlinked inheritance. The subject of our experiment is the fruit fly because it has a short, two week long life-cycle that allows…

Drosophila Melanogaster, or better known as the common fruit fly, is found all over the world and referred to as the cosmopolitan species (Mitrick, 2010). This fruit fly has three main body parts, which include the head, the thorax, and the abdomen. On males, the bottom half of the abdomen is black, while on the female, each segment of the abdomen is striped black. Drosophila have four main stages to their life cycle. These include: egg, larva, pupa and adult. The eggs small and translucent eggs…

Drosophila melanogaster is also known as the fruit fly. It “has played a central role in developmental biology during the twentieth century”. The fruit fly is considered a model organism for many reasons. Drosophila is low maintenance creatures that are easy to care for. Since they are such a small size, scientists are able to control numerous amounts of the Drosophila melanogaster at any given time. Drosophila reproduces many offspring and the offspring are created in a very fast fourteen-day…
