    primary literature, briefly summarize two studies that have used Drosophila as a model organism in a genetic or evolutionary context (Twenty Five Marks). The aggressive behaviour of the Fruit flies (Drosophila melanogaster) have been observed in a study to see the reaction of various neurobiological factors. Several techniques are used in the study including behavioural and genetic techniques. In the brain of the Drosophila melanogaster, neurotransmitters dopamine and octopamine as well as mushroom

  • Drosophila Melanogaster: The Meaning Of Fruit Fly

    1165 Words  | 5 Pages

    The meaning of Arthropod is an invertebrate animal that has a segmented body, jointed limbs, and commonly has a chitinous outer shell. This Phylum is specific to insects, spiders, arachnids, crustaceans, and myriapods. Drosophila Melanogaster is a species that comes from Phylum Arthropod. The common name for this species is fruit fly. If you are not sure what a fruit fly is, it is a 3mm long fly that is usually seen around spoiled fruit. Why are fruit flies even significant to biologists? They are

    Black. We hypothesized that Drosophila Melanogaster would prefer dim light over all colors, especially blue and black due to the fact that they have very short wavelengths which are lethal to the flies. However, results from 2 out of our 5 trials did not support the hypotheses. In the initial trial, Dim vs. Dim, we expected an equal number of flies on each side of the chamber due to the same lighting on both sides. Yet, the results proved otherwise, as Drosophila Melanogaster showed a strong preference

    The purpose of this experiment was to determine if there is natural selection against blind, white-eyed male Drosophila melanogaster, as well as if there is any interplay between selection and drift occurring in populations of different size. This was done by creating and monitoring both small and large populations and placing them in an environment with regular light or complete darkness. It was predicted that natural selection would occur against white-eyed males in the light trials, but would

    Testing Genetic Drift and Natural Selection in Drosophila melanogaster Materials and Methods The materials and methods are from (Welsh and Thompson 2016) Wild-body type (tan) and ebony body type Drosophila melanogaster were prepared before this procedure by chilling the flies to leave them immobilized . Drosophila melanogaster is an ideal organism for this experiment for they can be easily cultured. They can be cultured in less space in a temperature of 21-25(degree Celsius find degree sign)

    Tim Jenkins Brain Story 13 “The Thirsty Fly” Dr. Kroger Psy 375 11-16-16 In Weiner’s “The Thirsty Mind” article (2014), the neurostructures of a fruit fly were analyzed as it related to “thirst”. Kent Berridge has spent decades of his life devoted to the biological reward circuitry that exist. Berridge’s theory of rewards was broken down into 3 subcategories; liking, wanting and learning (Weiner, 2014). Different species have similar responses to a sweet taste: sticking their tongues out, which Berridge

  • Drosophila Life Cycle

    1426 Words  | 6 Pages

    Drosophila is a genus of small flies, belonging to the family Drosophilidae, whose members are often called “fruit flies”. One species of Drosophila in particular D.melanogaster, has been heavily used in research in genetics and is a common model organism in developmental biology. The entire genus, however, contains about 1,500 species and is very diverse in appearance, behavior, and breeding habitat. Scientists who study Drosophila attribute the species’ diversity to its ability to be competitive

    Life of Bees About eighty-five million years ago bees evolved into the ecosystem during the cretaceous period un-announced to many of Earth’s resident at the time. Bees where one of the first pioneers of humanities holocene period. “These industrious insects have been around roughly one-hundred twenty-five million years (give or take fifteen million years or so..) and although bee numbers are sadly declining, the remaining survivors continue to act as invaluable resources to our planet and its other

    Drosophilia melanogaster, known as the common fruit fly, is tan or light brown in color and usually have red eyes. The common fruit fly size is 3 to 4 mm (millimeters) and has a life span of 14 days. Drosophilia melanogaster is often favored amongst culture breeding due to how fast they breed and how short they live. It should also be noted that this specific specie also carry recessive genes that can cause an offspring to grow without wings which means that fruit fly cannot fly. Also, if a fruit

Here are some examples: (once again, the links are cool images) The Golden Ratio is responsible for the spiral patterns in the nautilus' shell, the aloe plant, the number and pattern of petals on flowers, sea shells, hurricanes and galaxies, and the shape of an egg and even the human face and hands have their bases in the golden ratio.

    Zebrafish advantages: handling, breeding and imaging techniques Zebrafish are one of the most important vertebrate model organism in biological research They are small (2-4 cm long) and robust; one pair of zebrafish can lay between 100-200 eggs in a single mating every week. The embryos after fertilization develop externally and the growth rate is very fast. For a large part of the development (till the larval stage) they are transparent and this is a great advantage for imaging during development

  • The Importance Of Risk Assessment In Genetic Counseling

    1. Describe risk assessment in genetic counseling Genetic risk should be estimated as precisely as possible as it is an important component of genetic testing and counseling, and for family decision making. It is always good to take out extra information from pedigree charts and genetic testing as it can improve the accuracy of risk assessment drastically. The risk can be calculated using Bayesian analyses. Among populations, families or individuals within the same family have significantly different

The dim light on Side B of the chamber would be favored because, in a previous study, D. Melanogaster were exposed to different illuminations, and “their favorite resting, grooming, and feeding places were determined with an infrared-sensitive camera.” Additionally, the study used infrared beams to collect data on the activity levels of the flies

    19524 Date: 11 September 2016 TA Instructor Name: Rintu Thomas Description of Unknown Mutant Allele Phenotype Drosophila melanogaster (fruit flies) are organisms that contain multiple types of mutations. A few examples of these mutations involve eye color, wing formation, body size and body color. When comparing the wild type version of D. melanogaster to mutant D. melanogaster with unknown code 651, it was shown that the mutant contained a mutation in the bristles located on the fly’s thorax

After comparing wild type and mutant flies, no differences were apparent

    Abstract: Drosophila Melanogaster are fruit flies. Previous research has shown that fruit flies are the most logical organism to use to study genetics. This is most likely because they reproduce and regenerate quickly and they are easy and relatively cheap to handle. In our experiment, we observed flies (F2) with unknown phenotypes that we had to discover. After discovering the phenotypes that we were looking for, we tried to figure out the parents (F2), which was the purpose of the experiment.

For biology and genetics, Drosophila melanogaster, the common fruit fly, has proven to be a suitable subject for over the last 100 years. In 1910, a small research group led by principal investigator Thomas Hunt Morgan at Columbia University first utilized Drosophila as a model organism to discover two fundamental concepts of genetics – chromosomal means

These results will provide abundant ground truth evidence for constructing neuronal computation models. Previous evidence suggested that asymmetry in Drosophila brain can be crucial for learning and memory. But none of the asymmetric circuity has been found nor have their roles in learning and memory been studied. With the single neuron connection prediction and validation, the function of the first, comprehensive

    A Demonstration of Chemotaxis Between Flies and Various Substances (Sugar vs Bacteria) Abstract: The purpose of this lab based on the Drosophila melanogaster (the common fruit fly) reactions. Since the fly has been studied and observed for many years, and known for its unique chemotactic attractions to different stimuli, it was an ideal organism for the study being conducted. In the experiment the purpose was to be able to figure out whether the flies would be more attracted to sugar or bacteria
