An overview of the genetics of the fruit flies

Introduction the purpose of our fruit fly experiment was to learn about genetics which is the study of dna, genes and traits we also studied mutations, which are the changing of an organism's genes and dna sequence which makes the organism different than that of its species, and the effects of it on our flies. Using fruit flies as a model organism allows us to more rapidly unravel the complexity of biological networks, many of which have similar structure and dynamics across flies, mice and humans thus fruit flies are an extremely powerful tool for the development of effective disease therapies. Fruit flies in the laboratory the fruit fly, also known as drosophila melanogaster , has the longest history in genetics and research out of all the model organisms although generally considered a pest by farmers because they lay their eggs in ripening fruit, in the laboratory the fruit fly has proved to be one of the most useful tools for . For example, fruit flies are inexpensive to maintain in the laboratory, have simplified genetics, and short generation times allow for quick experiments with high sample numbers then, key discoveries and important drosophila researchers, such as thomas hunt morgan are profiled.

Why fruit flies are a good genetic model for human disease study september 29, that's when studying fly and human genetics together becomes crucial the authors found that flies with mutations . But one species of fruit flies in particular by engineering fly genes so that flies bear characteristics of a genetic disease, the insects can serve as simpler . Drosophila melanogaster is a species of fly wildtype fruit flies are yellow-brown, and some of the genetics of sexual behavior have been characterized.

Fruit flies, like footballers, produce immense quantities of saliva the chromosomes inside the fruit fly's salivary glands are huge - a thousand times thicker than normal fruit fly genetics . Drosophila genetics: abstract – primary objective and experimental overview fruit flies are chosen as they meet all the criteria first and foremost, they . Melanogaster for genetic studies in 1907 the common fruit fly lives throughout the the environmental choices that fruit flies make in fruit fly behavior, so . Fruit fly phenotypes lucky for scientists, and maybe not so lucky for fruit flies, there are all kinds of ways that fly dna can be mutated to create interesting looking flies. Introduction the fruit fly drosophila melanogaster has been extensively studied for over a century as a model organism for genetic investigations it also has many characteristics which make it an ideal organism for the study of animal development and behavior, neurobiology, and human genetic diseases and conditions.

Video: thomas hunt morgan's fruit fly experiment in 1910, american scientist thomas hunt morgan conducted an experiment with a bunch of flies that changed our understanding of genetics. Fruit flies share 75% of the genes that cause disease with humans, so scientists can learn about human genetics by studying fruit fly genetics it is not only the flies themselves that the scientists are interested in, but also understanding the basic biology that all organisms have in common. Scientists discovered homeotic genes by studying strange transformations in fruit flies, including flies that had feet in place of mouth parts, extra pairs of wings, or two pairs of balance organs (called halteres) instead of wings some even had legs growing out of their heads in place of antennae . Brief summary drosophila melanogaster (common fruit fly), a member of the order diptera and family drosophilidae, is a small, yellow-brown fly +with an average length of 3 mm (miller, 2000) the native habitat of d melanogaster consists of tropical and temperate climates of africa, europe and asia (miller, 2000).
