The purpose of this experiment was to determine the F1 genotype of fruit fly traits using the phenotypic ratio of the F2 generation and to express these results of the unknown cross through a Chi-square model and Mendelian genetics. After the experiment‚ it was found that the parents held a heterozygous genotype through using the Chi-square model‚ and that the observed and expected values fall within the Chi-squared value which also falls into the p-value. The Chi-squared value was 5.64‚ the degrees

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 purpose of the study was to observe the role of diet during stress response at cellular and metabolic levels in fruit flies. Before the

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

Drosophila Melanogaster feed on fresh or decomposed fruit. We use a 1:1 ratio of instant medium to distilled water for the medium in culture vials that the flies will have to develop in. After making the medium‚ they have to be sprinkled with one or two grains of dry yeast to feed the flies. For the P1 and F1 cross‚ two culture vials V1 and V2 will be used just incase one vial doesn’t show as optimal breeding or medium as the other vial. When we isolate the flies and transfer them from one vial to the next
