pouring from everybody gnats tend to swarm up around most of the people out on the field. Gnats and fruit flies are very similar. The only difference between the two‚ is that gnats form big groups outdoors‚ while fruit flies are mostly found indoors. Either way they’re living‚ they’re both extremely annoying. There are many different types of gnats‚ which are Fungus Gnats‚ Drain Flies‚ Midges‚ Sand Flies‚ and Black

begin the lab‚ he/she must make a prediction about what gene the trait one are analyzing is on. The trait can either be sex-linked‚ or autosomal. To begin the lab‚ one must acquire a sample of flies to cross. These flies should be placed in a tube with an easily removable foam stopper. Use the flynap to knock out the fruit flies‚ and pour them out of the tube into a petri dish. Then place the petri dish on a stereomicroscope‚ and begin using a paintbrush to sort the flies by gender. Male flies have sex

Madison Fowler Fruit Fly Genetics: Dihybrid Cross Abstract Vestigial and ebony are two commonly studied mutations in fruit flies. Studies of these mutations have even been correlated with reproduction. In this study‚ a dihybrid cross is conducted between heterozygous vestigial and ebony flies in order to determine the acceptance of the nine to three to three to one ratio. If the results of this experiment come out as what is expected‚ about nineteen percent of the filial two generation should

Fruits Professor Kelechi Mezu Introduction to Biology – SCI 115 March 2‚ 2010 We use our sense of taste to differ if fruit is sweet or sour. That taste depends on the components in the fruit. Fruits contain fructose‚ acids‚ vitamin‚ starch‚ proteins‚ and cellulose. All of these components contribute to the taste of fruit. Fruits with high fructose levels tend to be sweeter whereas fruits with high levels of acid tend to be sour. Oranges however‚ have equal quantities of fructose and acids

using the fruit fly‚ Drosophila Melanogaster. A Cinnabar Brown female was crossed with Wild Type male. The flies were mated in a jar containing a nutrient medium and then placed in an incubator. The experiment was conducted over a period of 5 weeks. Cinnabar (cn) and brown (bw) are two loci in Drosophila with recessive eye colour mutations. Mutations in cn cause a bright red eye and mutations in bw cause a brown eye. Double mutants have white eyes. As predicted‚ all the F1 generation of flies were wild

In order to begin the experiment‚ culture vials for the flies were created. After wearing the proper safety gear‚ including but not limited to gloves and a lab coat‚ the fly food source was made using roughly an equal amount of distilled water and fly food. These were mixed until it had a mashed potato-like consistency. It mustn’t be too liquid-like as it will kill the flies; and should be solid enough to not slide around the vial. After obtaining and labelling a new vial‚ the food mash was placed
