occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by ensuring that the vials are kept horizontal until all of the flies fully recover from the anaesthetic. One possible error that may have occurred was that some of the adult flies may have accidentally been left in the vials

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

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 into a new vial containing a medium. After two weeks‚ when

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

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

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‚

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
