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

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

melanogaster: Monohybrid Cross & Sex-Linked Inheritance October 6‚ 2012 Abstract This lab involved a monohybrid reciprocal cross and a sex-linked cross utilizing Drosophila melanogaster fruit flies. After sexing the flies‚ placing them in media‚ and letting them cross breed‚ we analyzed and recorded the phenotypes that were observed. The P1 flies were anesthetized then sexed by observing their phenotypes and equally distributed into the media we made for their copulation

research is using this information to reduce the amount of anoxia related stress humans with pulmonary diseases experience. Methods Each condition was tested with a separate single group of D. melanogaster (cold bath - 8 flies and warm bath – 11 flies)‚ and all of the flies used were approximately 1-9 day old males. Each group of D. melanogaster was held in a container that provided adequate nutrients prior to the experiment‚ and then transferred to a drowning container that held no nutrients.

A Study Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila melanogaster‚ more commonly known as the fruit fly‚ is a popular species used in genetic experiments. In fact‚ Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can

Drosophila melanogaster: Mutant Fruit Flies Jessica E. Phillips Genetics 3301 April 13‚ 2012 Introduction: Drosophila melanogaster better known as the fruit fly can be found near rotting fruits‚ vegetables‚ or anywhere where there is food that has rotted and or fermented. (Potter‚ 2010) D. melanogaster has four different stages in its life cycle. The first stage of D. melanogaster is the egg which can last for about one day; then turns into a larva. The larva stage last for about 7-8 days

Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through

Ivan Chavez B1 Invasive Species: The Mexican Fruit fly An invasive species is a species that does not naturally take place in a particular area and with its arrival brings economic‚ environmental or human harm (1). Recently there has been a bigger emphasis on invasive species (1). They are threatening our agriculture and forests and causing major impacts to our cities (1). The characteristics that make the species thrive in their environment vary with each. Their characteristics

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
