Fruit Fly Lab Alycia Fletcher Biology IB HL March 25th 2010 Fruit Fly Lab Introduction Genes can either be sex-linked or autosomal. If a gene appears mostly in one sex chances are the gene is sex-linked and if it appears frequently in both sexes it is most likely autosomal. Using Drosophila melanogaster‚ also known as the fruit fly‚ we will determine whether the gene is sex-linked or autosomal. Drosophila melanogasters have a relatively short life span and are an excellent organism

Kayla Berezne Mrs. Cohen Honors Biology 24 March 2013 Genetic Predictions in the Fruit Fly The Drosophila melanogaster is a fruit fly with a very short life cycle. They can be winged or wingless‚ and have red eyes or white eyes. The different options are called alleles. Alleles are the variants of a specific gene‚ and one is received from each parent on each chromosome. (“What Are Dominant and Recessive?”). It was chosen to use winged females and wingless males to predict the offspring in this

Explanation The reaction was observed after 30 minutes because the reaction rate eventually slows down and the enzyme reaches its maximum potential. Since the enzyme is using the substrate so quickly‚ the substrates concentration depletes. That means the rate will slow down. Our graph shows that after about 40 minutes‚ the enzyme

predicted in the beginning of this experiment that under ideal conditions‚ we hypothesized that the results will eventually follow the Hardy-Weinberg expectations‚ which means the genotypes frequencies of the Drosophila melanogaster would remain constant; Therefore‚ no evolution had happened to the flies under the ideal conditions. After the chi-squared values were found in each week (table 1)‚ in the third generation where the chi-squared was found to be 0.32 which most likely fall between the two values

pulmonary diseases. Introduction Many animals have developed mechanisms that allow them to sustain anoxia comas for extended periods of time with little to no physiological consequences. This experiment is designed to test the amount of time it takes Drosophila melanogaster to enter and recover from an anoxia coma at different water bath temperatures. The purpose is to deduce the effects temperature has on the organism’s ability to enter and survive the anoxia coma‚ and generalize what body changes allow

Introduction Drosophila melanogaster is a species of Fly (the taxonomic order Diptera) in the family Drosophilidae. The species is known generally as the common fruit fly or vinegar fly. Starting with Charles W. Woodworth’s proposal of the use of this species as a model organism‚ D. melanogaster continues to be widely used for biological research in studies of genetics‚ physiology‚ microbial pathogenesis and life history evolution. It is typically used because it is an animal species that is

Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila melanogaster‚ more commonly known as the fruit fly‚ is a popular species used in genetic experiments. In fact‚ Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can lay hundreds
