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

zoologist and geneticist named Thomas Hunt Morgan is known for his research with fruit fly. Thomas Morgan was born on September 15‚1866 in Lexington‚ Kentucky. In 1886‚ he received his B.S. degree at the University of Kentucky. In 1910‚ Morgan saw that one male fly had a distinct difference about it. Instead of normal red eyes‚ this fly had white eyes (Allen). He wanted to test the breeding of Drosophila in fruit flies to understand the transmission of genetic traits through their generations. In order

AP Bio Essay #1 To address this problem created by the lab tech‚ I would set up an experiment like the one we did in AP biology to identify the molarity of the unknown sucrose solutions. First I would pour an equal volume of each solution into beakers labeled A‚ B‚ C‚ and D. I would also have a beaker of the same amount of distilled water to serve as a control for the experiment. Then I would obtain several baby carrots‚ 4 per beaker. I would mass the groups of 4 potatoes before placing them

Drosophila melanogaster is a fruit fly‚ about 3mm in length‚ and it is the insect that flies around spoiled fruit. A model organism has these traits: short life cycles and rapid development‚ small average size‚ big population‚ and fast reproduction (NCBI). Drosophila melanogaster meet all of the criteria for being a model organism. Also‚ fruit flies were used because they are very easy to handle and they require minimal resources to survive‚ as opposed to other organisms that might need more food

Christopher Kruzel Bios 221 April 4‚ 2012 Drosophila 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

stimulus that helps it search for the food (Stocker et al. 2007). There are flies such as dragon‚ house flies and various other flies in diptera order. Flies are attracted to sugar and seem to have certain neurons that activate upon encountering the sugary content. The compounds contained sugars‚ salts‚ bitter food‚ and certain other Molecules are detected by gustatory neurons‚ which are widely distributed in the body of the fly (Stocker et al. 2007 ). Neurons that influence feeding behavior are present

POPULATION GENETICS (FRUITFLY) NAME: Christopher N. Anah CLASS: BIOL 2108L INSTRUCTOR: DR. JAMES BATTEY OVERVIEW: In this lab the Drosophila melanogaster fly species were used to do genetic test crosses. Students were taught how to manipulate phenotypes‚ collect data from F1 through the F4 generations‚ and analyze the results.INTRODUCTION: The basic principles of genetics are very often shared by a vast array of organisms. For that reason‚ it is usually only necessary to study the genetic

To perform this study and observe the behaviors and reactions of Drosophila melanogaster and how they respond to different stimuli and repellents‚ the research members decided to use mutant fruit flies‚ for this reason they lacked wings‚ making their manipulation simpler. In order to carry out this study it was necessary to first obtain an adequate number of flies to observe them throughout the weeks. The research members had the flies accompanied with larvae in stock vials‚ and later transferred these

Fruit Fly Genetics Lab Kelly Hernandez 5/31/14 Drosophila melanogaster is a small‚ common fly found near unripe and rotted fruit. It has been in use for over a century to study genetics. Thomas Hunt Morgan was the best biologist studying Drosophila early in the 1900’s. Morgan was the first to discover sex-linkage and genetic recombination‚ which placed the small fly in the forefront of genetic research. Scientists have used Drosophila for many reasons. For one they are very easy to maintain‚

Nicole Ryan AP 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
