Vestigial Flies Experiment

The expected number of wild type flies in the F2 generation is 734.25 and the expected number of shaven bristle flies in the F2 generation is 244.75. This, again, exhibits a 3:1 ratio of normal phenotype to affected phenotype.

It was decided that there would be 80 vestigial flies and 20 wild type flies to total to an initial population of 100 drosophila. Next, the flies were anesthetized flies using Fly Nap. The flies were counted out to reach desired ratio, sexing the flies making sure there are equal amounts of males and females to be sure there is ample individuals to allow successful mating. The fly’s food was prepared by taking a frozen rotten banana, cutting it in half, mashing up the banana meat, and mixing yeast into it. The

In our experiment, we created three crosses; DxG,BxD, and BxG. In crosses BxG and BxD we found a rare mutant fly. This unusual mutant had a misshapen abdomen, deformed wings, and was pale in color. While the mutant was rare, due to the fact that it popped up in both those populations, we hypothesized that this genetic mutant had already previously been discovered and named.

California grizzlies had been around earth for centuries before humans invaded their territory. In the state of California, “some [California grizzlies] grew to a formidable height of 8 feet and weighed 2,000 pounds, according to a history of California written in 1898”, which made them targets for the various resources they could provide naturally (Staff). When miners came to California to harvest the gold, they began to see the grizzlies as a threat. In “less than 75 years after the discovery of gold… every grizzly in California had been tracked down and killed” making it extinct shortly after (Staff). Grizzlies in California were hunted and killed because they were seen as dangerous and hunters would harvest them for their resource of warm

For the dark environment we cut out a sheet of black paper and taped it to the top of the observation chamber, for the light environment two flashlights were above the chamber. A funnel was used to put the bugs in the middle and keep them there until the timer was started. After thirty seconds when the pill bugs were released our group counted how many bugs were either in the neutral, dark, or light section of the observation chamber this is how the data was collected. This experiment had two trials, so the data, that was collected during both trials were averaged out. During the second experiment that was conducted the pill bugs were once again placed in the middle of the observation chamber with the funnel, but this time one section of the chamber had soil with three drops of water, while the other section of the chamber had soil with 3 drops of vinegar. Once thirty seconds had past after the bugs had been released each member of the group counted how many bugs were on each sections of the chamber. This experiment was done twice and then the data was averaged out the data. This method of collecting data was chosen because this was the simplest and most efficient way of collecting

It may be a New Year, but that doesn’t mean the winter is anywhere close to over. In fact, Ludlow, Kentucky could be facing some serious cold and snow in the next couple of weeks, and it always pays to be prepared. That’s why Ideal Supplies, your local hardware store, recommends that you stock up on your salt/calcium pellets now before it’s too late. You don’t want to be desperate for ice remover when there’s already ice on the ground.

Heterozygotes, which have the wild type phenotype, have normal sight which gives them the advantage of finding a mate and have a better success with attracting a mate with their courtship song (Kyriacou et al, 1978). The male heterozygous Drosophila had a better advantage at mating than the homozygotes, which were the ebony, and therefore we predict there will be more wild type by the end of the experiment.

You can collect individual flies that you have generated (for use in future experiments) by dragging them

we said goodbye and placed them in the fly morgue. We allowed the F2 larval

1a. The purpose of this experiment was to study the relationship of the distribution of stable flies to certain environments and to understand how and why it affects their survival. A stable fly or (Stomoxys Calcitrans) is a fly that sucks the blood of domestic animals and humans. Natural enemies of the stable fly include beetles and mites which devour eggs and larvae, small parasitic wasps known as (Spalangia) are predators to the stable fly, attacking fly pupae.

The AG was established by Churches that were looking for authentic Christianity. William Seymour, a Black pastor, preach radical reconciliation and the restoration of spiritual gifts. This caused Pentecostalism to be seen on a worldwide stage. The founding fathers (unnamed) of the AG saw this revival and decided to organize it, hoping to create doctrinal stability. They formed the first General Council, working to promote doctrinal stability and missions. The first elected officials of the General Council were Eudorus N. Bell as the chairman and J. Roswell Flower as the secretary. Flower also became the first executive presbytery.

An experiment was conducted to test the effects of different carbon dioxide concentrations on the mutations of later generations of Drosophila melanogaster. The model organism, Drosophila melanogaster, commonly known as the fruit fly is used widely in many fields of developmental studies because of its traits of fast reproduction rate, Hox genes, and low maintenance. In addition, the type of Hox genes tested in the Drosophila melanogaster, or the gene most susceptible to alteration from the increased CO2 emissions, are the Hom-C ANTp genes. The subset of genes is relatable to the Hox-A A6 genes in humans. It was hypothesized that an increase in the CO2 concentrations will cause the future generations of fruit flies to exhibit signs of genetic

One possible error that may have occurred was that some of the adult flies may have accidentally been left in the vials with their offspring,

A common trait that is associated with human beings is adaptation whereby individuals tend to develop similar behaviors as they evolve in life. Adaptation refers to situations where a common behavior or character is found to be followed by current societies in the same ways as those in past generations (Becker, 2014). Once a common trait is adapted by one individual and later on an entire society follows the same it becomes hard to break it down. Therefore it leads to this trait being followed through by all generations to come later as it has become a functional adaptation.

Some larva containing vials had hatched into flies. Counting of the flies began at this point. As flies started to grow, at different rates for each vial, with in the first seven days after all larva had hatched the flies were counted. The procedure was done according to theDrosophila manual (45-2620)
