Drosophila Melanogaster: Decapentaplegic gene
The fruit fly, Drosophila Melanogaster, has been used for years as a model for genetics. The flies are small and easy to maintain in a lab, cost-efficient, and have a quick life cycle, all qualities that make this a prime organism to utilize for genetic research. The data and conclusions derived from this research can have long term effects on not just the understanding of genetics but on the treatment of human diseases. A disease of great personal and recent national interest, amyotrophic lateral sclerosis

As dpp diffuses through the neighboring cells, it activates either the type I receptor, Thickveins (TKV) or saxophone (sax), or both. TKV must be activated for any response to dpp and sax is only activated at high levels of dpp. TKV is responsible for the growth of the wings. If the signal is overly amplified it can result in the overgrowth of the longitudinal wing vein. If dpp is not signaling to grow more, then it is captured and destroyed by the cell which contributes to this gradient of …show more content…
These gene is a vital part of the integrated process of development. In drosophila, it determines the dorsal-ventral axis and also controls the development of the fly’s wings. Without this axis, the determination of where appendages develop can be incomplete or incorrect resulting in wings or feet in the wrong places. Major mutations during development are often lethal. In addition, wing development is extremely important for both survival and reproduction in drosophila. Without wings, the fly will have great difficulty escaping any dangerous situations such as predators or drowning and it will also struggle with courting (because they cannot make the sound with their wings) and mating. There is still a significant amount of research that can be done on this gene. The numerous interactions can be more closely studied in order to understand the true extent of dpp’s effect on development. In addition, because dpp plays such a vital role in development across taxa including in sea anemome, frogs, and humans, research could be completed to better understand development and possibly assist in the rapidly developing field of in vitro fertilization in humans. In addition, this gene may be studied to see if it has as significant effect, as it does in drosophila, on adult appendages. The studies of this gene and where it can be found across different taxa is not the only thing that can make a remarkable change in science. It

    The second gene is Plexus (px) located at 2.100.5. This gene plays a role in biological process expounded with imaginal disc-derived wing vein morphogenesis. The gene has 61 reported alleles, and these alleles manifest themselves in wing vein, leg, wing, and eye (Kahsai et al. 2665). Therefore, it can lead to disruption of wing normal venation pattern which was observed in wild-type D. Melanogaster. The third gene is known as Blistered (bs) located at 2.107.3.…

    We hypothesized that curly wing flies would have difficulty courting past the flapping of its wings to create a “love song”. The FraxE flies are model organisms of a mutation that causes mental retardation and various behavioral problems. We did not expect very much courtship at all in this group. Lilli flies were similar to the FraxE model except they had the protein that was lost with the mutation placed roughly 50% back into them. We thought the flies with this mutation would have more courtship then the FraxE but less than the curly wing fly.…

    The simple but revolutionary organism Drosophila melanogaster has intricate properties that are studied to find its relations with human genes. Not only is D. melanogaster a model organism for its rapid growth, inexpensive culturing, and easy modifications, the Drosophila can provide more in-depth scientific analysis that can solve human diseases. The model organism D. melanogaster is studied to find ground-breaking research in neurology, sleep, cancer, and drug discovery. The multivariable effects in cancer can be studied by observing D. melanogaster because of its tumorigenesis caused by genes and its surrounding environment. The development of tumors in D. melanogaster is similar to the pathway of a tumor in a mammalian cell as it undergoes…

    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 characteristics that make them excellent subjects for genetic studies.…

    The effect of being exposed to light effected the phenotype of the Drosophila melangaster. The phenotype frequencies changed for both the red eyed and white eyed fruit flies (Figure 1). In the populations that were in complete darkness, the white and red eyed phenotypic ratio stayed almost constant throughout the whole experiment for both male and female fruit flies, which was shown with a “V” formation (Figure 1). This trend did not continue, though when it came to the phenotypic ratio for both eye colors when they were in the cage that was exposed to light. The red eyed phenotype in the male fruit flies increase by .25 but only .223 when it came to the females during the whole experiment (Table 1).…

    The apterous gene mutations is a recessive trait that is inherited causing a varying phenotypes such as different wing deformities. Other phenotypes observed are the decrease in life span and female sterility. Ap is required to regulate gene expression needed for the development of Drosophila wings and haltere discs. Decreased ap activity due to the overexpression of dLMO results in wing mutations. The phenotypes displayed in apterous mutants are places them at a disadvantage compared to wild type flies.…
