    Traits are inherited in a variety of ways ranging from dominate or recessive and sex-linked or autosomal. Using different model organism, scientists are able to study inheritance patterns of many generations in a short period of time. Different model organisms are utilized in many different ways. In the case of this experiment, a model organism must have a rapid rate of maturation and reproduction. The use of Drosophila (fruit fly) was chosen for its fast gestation period and ease of trait comparison between generations (Cartier and Stewart, 2000). This allows for scientists to gather multiple generations worth of data in a short period of time to see the inheritance pattern. This will allow them to distinguish if the trait was a dominate or…

    The Drosophila melanogaster, also known as the fruit fly, was the primary research subject for Thomas Morgan. In 1910, Morgan used the fruit fly as an experiment to discover new mutations which could represent new species. Using the flies to research about heredity gave way to Gregor Mendel’s confirmation of his Chromosomal Theory of Inheritance which suggests that the chromosomes are the carriers of genetic information. The sex of the fly is important when culturing Drosophila and making…

    Introduction When analyzing biological processes and development, Drosophila melanogaster is an ideal organism to utilize. Compared to other organisms, the functions of D. melanogaster are easier to manipulate due to its quick sedation time from carbon dioxide. These flies can be sedated in less than ten seconds with a carbon dioxide flow rate of 5L/min. D. melanogaster also produces offspring in a short amount of time (roughly 10 days at 25 degrees Celsius), which makes it a desirable species…

    The Spotted Wing Drosophila, (SWD) scientifically known as Drosophila suzukii Matsumura, is not your average fruit fly. Going by multiple aliases such as the cherry fruit fly or the cherry vinegar fly, the SWD has made a rather unattractive name for itself. The Spotted Wing Drosophila’s Taxonomic Tree is as follows: Domain: Eukaryota, Kingdom: Metazoa, Phylum: Arthropoda, Subphylum: Uniramia, Class: Insect, Order: Diptera, Family: Drosophilidae, Genus: Drosophila, and Specieis: Drosophila…

    This review article describes how the mating decision of Drosophila fruit flies is dependent of first the male’s choice to mate and then the female’s choice to accept or reject the male. The article simplifies the mating by the neurobiology behind the male’s choice and then the female’s choice. Furthermore, the article describes how males rely on chemical signals to detect suitable courtship objects and distinguish female flies from males. According to the article, males courtship is based on…

    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…

    The Drosophila melanogaster has been a novel model organism for researchers for over a century studying various species at a molecular level. Because Drosophila has a short life cycle and easy to manipulate advocates Drosophila as a good model organism. The insight into molecular mechanisms in studying this species is why it has been used for such a long period. This organism is easy to manipulate to observe the changes over time, and because of this the variability among these species allows…

    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 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…

    Genetics is a fundamental part of life as it is related to how we receive and develop traits from our parents and what could be given to our children. The concept of genetics was started around 1856 by Gregor Mendel who conducted experiments with pea plants and established many of the rules of heredity now used in modern genetics. According to Corcos and Monaghan (1984) Mendel did not consider the two laws written by him to be laws at all but to be assumptions or a hypothesis that were later…
