A short story research paper is a type of academic paper that involves analyzing a short story in order to understand its themes, characters, and literary elements. To write a short story research paper, you will need to start by reading the short story closely, taking notes on your observations and ideas as you go. Then, you will need to formulate a thesis statement that encapsulates your main argument about the short story. This thesis statement will guide the rest of your paper as you develop your analysis and support your argument with evidence from the text.

To give you an example of how a short story research paper might be structured, let's consider the short story "The Cask of Amontillado" by Edgar Allan Poe. One possible thesis statement for this short story might be: "In 'The Cask of Amontillado,' Edgar Allan Poe uses irony and symbolism to explore the theme of revenge."

In the introduction of your paper, you might provide some background information on Edgar Allan Poe and the historical context in which "The Cask of Amontillado" was written. You might also briefly summarize the plot of the story and introduce your thesis statement.

In the body of your paper, you could then analyze specific examples of irony and symbolism in the story to support your thesis. For example, you might discuss the use of the cask of amontillado itself as a symbol of the narrator's desire for revenge, or the use of the catacombs as a metaphor for the narrator's own buried resentment. You might also analyze the use of irony in the story, such as the narrator's feigned concern for his victim's well-being, to show how Poe uses this literary device to reveal the narrator's true motives.

Finally, in the conclusion of your paper, you might summarize your main points and restate your thesis, highlighting the significance of your analysis. You might also consider discussing the broader implications of your argument and how it relates to other works by Poe or to the literary tradition more broadly.

Overall, a short story research paper is an opportunity to deeply analyze a specific work of literature and make an argument about its meaning and significance. By carefully reading the text, forming a clear thesis statement, and supporting your argument with evidence, you can produce a well-written and thought-provoking research paper on a short story.

Fruit Fly Cross Breeding Experiment

drosophila melanogaster genetics experiment

Identical alleles in an organism signify that the organism is homozygous for that gene. Many heredity variations can be studied in these flies. Although these fruit flies may seem like very simple and insignificant organisms, they allow us to do research that may otherwise not have been possible. The author outlines the key aspects of asexual and sexual reproduction. For cross set E, both the sex and phenotype for each fly was recorded. Coverage is shown separately for T0, and TN ctrl and TN high sugar.

After the separation of the 2 sexes, the unwanted flies should be discarded immediately into the morgue a bowl of mineral oil or detergent in water. The adult emerges from the puparium about a day after the eyes have formed. The sex and mutations of each fly were recorded. Learn More Abstract The main purpose of the lab report was to investigate the concept of genetic cross among Drosophila melanogaster fruit flies. We also thank members of the Ayroles and Andolfatto labs for their general support and helpful scientific discussions. In terms of sex, that yields 37. The head is composed of 6 fused segments, a pair of antennae with plumose aristae, and a licking proboscis without mandibles.

The wild type phenotype for eye color is red, while the mutant phenotypes are sepia and white. Knowing how fast flies mature and breed, one of the earlier larvae to reach adult form could have gotten enough extra time between the days to breed. The reciprocal mating of the 2 strains is also done. . Learn More In addition, it is also important to determine the sexes and the mutations of the Drosophila accurately.

This mutant gene was expressed as a white color in the eyes. I hope that the research conducted with these flies will allow for greater discoveries in various fields of science that will contribute to the advancement of mankind. They also have abundant genetic variation in a relatively small genome. The chi-square results of the class data show that there are were slightly more red-eyed flies spawned than white-eyed flies. The emergence of the adult fly is preceded by the appearance of dark elliptical wings and the appearance of large, pigmented eyes. A fully transformed adult fly emerges out through the anterior end of the pupal case.

The parents are removed in order to prevent interference with the data The F1 flies are taken out and placed into a separate vial with FlyNap to complete incapacitate them for observation. The experiment was aimed at understanding how the Mendelian genetic principles are manifested in the breeding patterns of Drosophila. An example of this is the gene that codes for eye color in Drosophila, which can result in red, sepia, white, or brown phenotypes. As the pupa undergoes this transformation within the puparium, the cuticle of the exoskeleton hardens and darkens. A limitation of this experiment is the fact that we only counted progeny during one session. Gowinda: unbiased analysis of gene set enrichment for genome-wide association studies. In terms of eye color, there were supposed to be about 50-50 whites and reds.

Whether they are stuck to the paste or escaped the lab, that gives us less flies to count. To do this, we mated D. The p-value for cross set C was between 0. Once it was evident that many F1 offspring had matured into adults, the flies were put to sleep and dumped onto notecards. Cross 2 experienced a similar phenomenon in F1 where flies have traits they should not have.

For example, if two genes are on the same chromosome, the assortment of their alleles will not be independent. We then added the parent generation flies needed for all three vials and sealed it with the plugs. See Text S6 for additional details. Using the Chi-squared model, it is possible to analyze the strange ratios in the Punnett square and build an experiment to test the probability of this ratio happening. The egg stage lasts a single day and from it emerges a larva plural larvae.

However, the resulting F2 generation whose results are listed below indicates that the results of the experiment bear an unexpected ratio. This paper describes the results of an experiment to measure the effect on mean population fitness of recombination in the second chromosome of Drosophila melanogaster.

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. Harpak provided helpful comments on the analyses. The flies were observed under a dissecting scope and found to be either male or female based on the body morphology. Extending from the anterior dorsal surface, there is a pair of egg filaments. Details on the simulations and analyses of simulated data are provided in the SI Methods see Text S5. Methods The experiment began by sorting out the flies according to phenotype and sex and then selecting four from each sex.
