Introduction: Drosophila 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

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

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

UCSC since 2007. his current research includes using Drosophila fly to study genetic and development biology. I was impressed with Lee’s techniques into studying Alzheimer’s with the Drosophila fly(fruit fly). While I was reading the research paper‚ I had this unsettling question to why using precisely Drosophila fly to study Alzheimer’s. However‚ during his lecture or presentation‚ I came to find out that the main reason he was using fruit flies was that they grow up fast their life spans approximates

Drosophila melanogaster - Sex linkage and inheritance of genes through cross breeding Abstract This experiment looks at the relationship between genes‚ generations of a population and if genes are carried from one generation to another. By studying Drosophila melanogaster‚ starting with a parent group we crossed a variety of flies and observe the characteristics of the F1 generation. We then concluded that sex-linked genes and autosomal genes could indeed be traced through from the parent generation

Drosophila melanogaster: Mutant Fruit Flies Jessica E. Phillips Genetics 3301 April 13‚ 2012 Introduction: Drosophila melanogaster better known as the fruit fly can be found near rotting fruits‚ vegetables‚ or anywhere where there is food that has rotted and or fermented. (Potter‚ 2010) D. melanogaster has four different stages in its life cycle. The first stage of D. melanogaster is the egg which can last for about one day; then turns into a larva. The larva stage last for about 7-8 days

BIOL 323-02 TTH 12pm-2pm Drosophila melanogaster: Monohybrid Cross & Sex-Linked Inheritance October 6‚ 2012 Abstract This lab involved a monohybrid reciprocal cross and a sex-linked cross utilizing Drosophila melanogaster fruit flies. After sexing the flies‚ placing them in media‚ and letting them cross breed‚ we analyzed and recorded the phenotypes that were observed. The P1 flies were anesthetized then sexed by observing their phenotypes and equally distributed

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

Introduction 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

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
