    Madison Fowler Fruit Fly Genetics: Dihybrid Cross Abstract Vestigial and ebony are two commonly studied mutations in fruit flies. Studies of these mutations have even been correlated with reproduction. In this study‚ a dihybrid cross is conducted between heterozygous vestigial and ebony flies in order to determine the acceptance of the nine to three to three to one ratio. If the results of this experiment come out as what is expected‚ about nineteen percent of the filial two generation should

    Fruit Fly Lab Introduction The major topic of this experiment was to examine two different crosses between Drosophila fruit flies and to determine how many flies of each phenotype were produced. Phenotype refers to an individual’s appearance‚ where as genotype refers to an individual’s genes. The basic law of genetics that was examined in this lab was formulated by a man often times called the "father of genetics‚" Gregor Mendel. He determined that individuals have two alternate forms

    Introduction The fruit fly or Drosophila melanogaster is ideal for classroom experiments. They are inexpensive‚ easy to nap‚ breed‚ as well as observe. It was very important to be able to tell the male and female flies apart from one another. The males are known to be usually smaller in size than the female flies and have bristles on their forelegs while the females lack this appearance. Also the males have a black or dark round end whereas the females have striped pointy ends. The Drosophila flies are small

    melanogaster commonly known as the fruit fly is considered a model organism in the field of genetics because of its short life cycle of about 10 weeks and the ability of the fly to produce a relatively large number of offspring at 50-70 eggs per day upon female maturity. The physical size of the male and female Drosophila is approximately 2.5 to 3 mm respectively Drosophila allowing for minimal storage space in a laboratory setting. The intricate nervous system of the fruit fly has made them very vital to

    Biology 2/2/15 Block 1 Introduction and Background Drosophila melanogaster or more commonly referred to as “fruit flies” have been used for genetic research for over 100 years. During his time at Harvard university‚ Charles W. Woodworth is credited with being the first to suggest fruit flies be used for genetic research. A century later‚ fruit flies are the most widely used eukaryotic organism for genetic research (Drosophila). Their ease of use and rapid rate of reproduction

    Introduction In this lab a study of fruit fly genetics was done these creature are readily used for genetic studies .they are easy to maintain. And the females lay a lot off eggs which develop in about two weeks. Fruit fly’s have for distinct stages‚ the egg‚ larva‚ pupa and adult. the egg and larva stages last for eight days‚ the pupal stage last for six days and then the adult stage which last for many weeks this period of growth is called instars. In this lab a dihybrid cross was performed to

    The Dumpy Sepia X Wild Type Dihybrid cross using Drosophila Melanogaster. Abstract An experiment was performed on the fruit fly (Drosophila Melanogaster) in order to investigate Gregor Mendel’s postulates and determine if his laws were in fact correct. This was done by crossing Virgin Wild type females with Dumpy sepia males‚ and then inter-crossing their progeny (the first filial generation) in order to produce the second filial generation which was then studied. The results of this were designed

    The history of fruit flies is considered a tradition. Research of these flies initially entered labs 100 years ago. Thomas Hunt Morgan‚ who lived from 1866 to 1945‚ was the founder of drosophila genetics. Thomas preformed his research in Morgan lab at the Columbia University in 1910. Here was when they found a famous mutation‚ know as the white-eyed fly. Quite an accomplishment was this discovery‚ but the end of the 1980’s there were 3‚000+-recorded mutations. Now drosophila is very popular; so popular

    Drosophila melanogaster is a common fruit fly that has been useful for most experiments in the study of Genetics. The male and the female fruit fly are similar and different in regards to how they look‚ structurally. They are similar because both genders have a head‚ thorax‚ proboscis‚ antennae‚ eyes‚ and mouth parts. However‚ males are smaller than females and have about five abdominal segments as opposed to the seven that the female has. The life cycle of these fruit flies consist of egg‚ larvae‚ metamorphosis
