Drosphila melanogaster (fruit flies) and set up genetic crosses in order to determine the pattern of inheritance of certain mutant traits. The traits for which we will examine the pattern of inheritance are apterous (wingless)‚ vestigial (crippled wings) or white eyes. These are all mutant strains. The normal condition (winged and red eyes) is referred to as the wild type strain. Objective: The intial cross mates homozygous mutant fruit flies with homozygous wild type fruit flies in order to produce

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

Genetics With Drosophila Flies Josh Derrall Lab Group: Dana Gilkes James Lupo Olivia Giannola December 4‚ 2012 Prof. Hunter Introduction Genetics is a topic that has been studied for hundreds of years. One of the most notable geneticists was Gregor Mendel. Mendel studied basic inheritance patterns and gene expression using pea plants. Mendel determined that the offspring of two parents contains one gene from each parent (McKusick 1983). However‚ since Mendels discoveries

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

The fruit fly Drosophila melanogaster are an excellent specimen for research in genetics. Many reasons are that they have a rapid reproduction rate‚ easy to care compared other animals and less expensive. Researchers have determined the nucleotide sequence of nearly the entire 120 megabase euchromatic portion of the Drosophila genome (Cite). Drosophila has a simple genetic arrangement of only four chromosomes which contains three autosomes and one sex chromosome according to(--) and because of this

Model organisms are species that are studied to understand the biology of other organisms‚ usually humans. Fruit flies share 75% of the genes that cause certain diseases with humans. Therefore scientists can learn about human genetics by studying fruit fly genetics. This falls under the bigger principle of understanding the basic biology that all organisms have in common. Common fruit flies like Drosophila are useful when studying genetics for several reasons‚ such as their small size that makes

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 to figure out the transmission‚ Morgan did an experiment of cross testing

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

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

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
