other organisms‚ usually humans. Fruit flies share 75% of the genes that cause certain diseases with humans. Therefore scientists can learn about human genetics by studying fruit fly genetics. This falls under the bigger principle of understanding the basic biology that all organisms have in common. Common fruit flies like Drosophila are useful when studying genetics for several reasons‚ such as their small size that makes them easy to utilize in genetics experiments‚ they are low “Low Maintenance

influence the population of fruit flies? 2. Do fruit flies reproduce faster in cool or warm temperatures? ie. Is the reproduction rate of fruit flies faster in warm temperatures or cooler temperatures? Hypothesis: Using two separate 750g boxes of peaches‚ one box placed in a warm environment (in front of a window allowing direct sunlight onto the peaches)‚ while the other is placed in a cool environment (beneath the kitchen sink)‚ over a period of two weeks‚ fruit flies will tend to reproduce at

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

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

The fruit fly Drosophila melanogaster are an excellent specimen for research in genetics. Many reasons are that they have a rapid reproduction rate‚ easy to care compared other animals and less expensive. Researchers have determined the nucleotide sequence of nearly the entire 120 megabase euchromatic portion of the Drosophila genome (Cite). Drosophila has a simple genetic arrangement of only four chromosomes which contains three autosomes and one sex chromosome according to(--) and because of this

Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2‚ 2014 I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic
