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.

Mendelian Genetics of Drosophila

What genetic principle does this illustrate? The exoskeleton of the third instar is not shed, but instead develops a thick cuticle, which will eventually become the puparium , or a place in which the pupa can undergo metamorphosis, the 1 transformation to a sexually competent adult. After every F1 generation fly was counted for each cross set, they were dumped into the morgue. Next generation software for functional trend analysis. Comparison of two statistical approaches to test for allele frequency changes with age. . Those two F1 flies could bring in F2 flies during the F1 count through sexual reproduction. Males can also be identified by the presence of black pigmentation at the tip of the rounded abdomen.

Microsoft Excel was used to generate tables and Chi-Squared Values for the lab. Genetics of Drosophila melanogaster Introduction: Gregor Mendel revolutionized the study of genetics. Differentiation between Male and Female Drosophila Media Preparation Drosophila melanogaster, like other animals, requires an optimum temperature for its survival, growth, and breeding. As a result, we fail to reject the null hypothesis of the chi-square test for both crosses. Many heredity variations can be studied in these flies. According to this data, the number of male flies with wildtype red eyes 10 was equal to the number of male flies with white eyes 10.

Those remaining F1 flies could have extra time to breed since they are more mature than the remain larvae and pupae. Drosophila melanogaster is a dipterous, holometabolous insect. It is white, segmented, and wormlike. After a while the adults emerge. Currently whole genome sequences are available for 161 different mutants. Although an experiment that uses such organisms might take longer, the shift is likely to improve overall accuracy levels. That could have given the F1 flies enough time to breed and spawn F2 during the days we counted for the F1 flies only.

Since both parents were found to be heterozygous for eye color Bb , the dominant red allele masked the effect of the recessive sepia allele. It is used as a model organism for research studies especially in the field of genetics and evolutionary biology. Coverage is shown separately for T0, and TN ctrl and TN high sugar.

They also have very simple food requirements. The lack of time in a class period was detrimental with the incapacitation step for the counting process. Biology drosophila drosophila is the best genetic model for innumerable laboratory experiments because they are small in size. . Furthermore, drosophila are diploid organisms which means that their chromosomes are arranged in homologous pairs and for a simple phenotypic trait, there will be two copies of the gene one on each chromosome.

Cross 2 Null: The distribution of the F1 and F2 offspring of the white female drosophila x wild male drosophila in cross 2 will be 50% red eyed females and 50% white eyed males in the F1 generation and 25% Red Females, 25% White Females, 25% Red Males, and 25% White Males or 50% red and 50% white in the F2 generation.

Since these p-values were larger than 0. In the common parlance, a larva is simply a fly maggot. The flies from the assigned cross set were observed under a dissecting microscope, and the eye color and wing presence was recorded for each fly. Males and females were separated and mutations were observed and recorded. From this work, it is clear about the history of genetics and some possible disorders. This null distribution is plotted for 100 subsamples.

This indicated that the red-eyed female flies were heterozygous for eye color X +X w , since the contribution of a mutant allele from both parent flies would result in offspring with red eyes and white eyes in equal proportions.

The ratios that are used in the F1 generation are selected randomly but under controlled environment. Our results contained a few sepia flies, which ultimately leads us to reject the null hypothesis. After 6 hours of emergence, the adult fly attains the ability to participate in reproduction. Genome-wide analysis in Drosophila reveals age-specific effects of SNPs on fitness traits.
