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

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

The scientists‚ Seema Sisodia‚ Puja Verma and Bashisth Narayan Sing explain there research in “The Effect of Diet Quality and Associated Metabolic Changes in Adult Stress Response and Life-History Traits in Drosophila Ananassae” The D. ananassae used in the experiment are flies collected from fruit and vegetable india in October 2010. The purpose of the study was to observe the role of diet during stress response at cellular and metabolic levels in fruit flies. Before the

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

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

FRUIT FLY PURPOSE: The purpose of this lab is to determine what genetics are dominant and which one is recession in the fruit fly and to see what genetics are past down from generation to generation. INTERODUCTUON: Mendel’s pea did and experiment that was demonstrates genetic inheritance. When his experiment he found out that genes are past down from generation to generation.

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 of 0.148 and 0.455. These two values correspond to a probability values of 0.70 and 0.50‚ and these two values lay to the left of the p- value of 0.05‚ which means the null hypothesis presented

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
