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

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

Biology Lab Report 7 “Independent Assortment & Dihybrid Cross” 10-22-2013 Biology 202 Introduction: In genetics‚ when crossing a purebred white flower with a purple flower‚ we might expect its offspring to be a blend of both colors. Instead‚ we see that its offspring is purple as well. This is led to be by one trait being dominant over another trait. Gregor Mendel came up with a theory that each member of a pair of homologous chromosomes separates independently

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 get data results

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

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

A Study 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

Block 1 January 24‚ 2011 Introduction & Background Fruit flies have made a huge contribution towards knowledge about genetics‚ but for most people‚ they are just annoying insects that are attracted to their fruit. Their scientific name is Drosophila melanogaster‚ and to scientists‚ they have been a key to understand many principles of heredity including sex linked inheritance‚ epistasis‚ multiple alleles‚ and gene mapping. Fruit flies were the first organisms to be used for genetic analysis

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
