Fruit Fly Introduction Essay Example for Free

Fruit Fly Introduction Essay The purpose of this lab is to understand how each offspring inherits its genotype and how its phenotype reflects it. Sex chromosomes determine the sex of the offspring, and the autosomes consist of all the other chromosomes that determine phenotypic traits. Dominant traits are the genes that are expressed, while the recessive traits are masked by the dominant traits. We used Drosophila melanogaster (fruit fly), mutating the female fruit fly with a scalloped gene to change the phenotype of its offspring and using males with genes showing wild-type. Placing WT males and SD females in the same vile, we provided the flies an atmosphere to mate, giving us offspring with mixed genotypes and phenotypes. This experiment will reflect the breeding of fruit flies and how genes are present within adults as well as passed down through the offspring. Our four hypotheses related to mode of inheritance that was used to pass the gene. The mode of inheritance for the scalloped gene is autosomal dominant. The genotype of the female parent is homozygous dominant. The male parent genotype is homozygous recessive. From this hypothesis we expect all of the offspring to have a heterozygous genotype, and the offspring would all be scalloped†¦. The mode of inheritance for the scalloped gene is autosomal recessive. The genotype of the female parent is homozygous recessive. The genotype of the male parent is homozygous dominant. From the hypothesis we can expect the offspring to have heterozygous genotypes, but the offspring’s phenotype would be wild type†¦. The mode of inheritance for the scalloped gene is sex-linked dominant. The genotype of the female is homozygous dominant. The genotype of the male parent is hemizygous recessive. From this hypothesis we can expect all the female offspring to be heterozygous and all the male offspring to be hemizygous dominant. Both male and female offspring would be scalloped†¦.. Finally, the mode of inheritance for the scalloped gene is sex-linked recessive. The genotype of the female parent is homozygous recessive. The genotype of the male parent is hemizygous dominant. From this hypothesis we can expect all the females to have heterozygous genotypes and all the male offspring to have hemizygous recessive genotypes. In this prediction, all the male offspring would be scalloped, while the females would be wild type†¦.. The hypothesis that stated the mode of inheritance for the scalloped gene is autosomal dominant, and the mode of inheritance for the scalloped gene is sex-linked dominant predicted that all of the offspring are scalloped. To set up the reciprocal cross, the mutant gene was given to the male rather than the female from the first experiment and the female received the wild-type. The first hypothesis stated was that the mode of inheritance for scalloped is autosomal dominant. In this hypothesis the female genotype was homozygous recessive while the male’s was homozygous dominant. The offspring from this cross had heterozygous genotypes and expressed the mutant phenotype. †¦. The mode of inheritance for scalloped is autosomal recessive. In this cross, the male parent had a homozygous recessive genotype, while the female had a homozygous dominant genotype. The result of this was that all of the offspring had a heterozygous genotype and expressed the wild type phenotype. †¦ The mode of inheritance for scalloped is sex linked dominant. In this cross the female parent had a homozygous recessive genotype while the male had a hemizygous dominant genotype. The female offspring from this cross were heterozygous and expressed the mutant phenotype, while the male offspring had a hemizygous recessive genotype and expressed the wild type phenotype. †¦ The mode of inheritance for scalloped is sex linked recessive. In this cross, the female parent had a homozygous dominant genotype while the male parent had a hemizygous recessive genotype. The female offspring of this cross had a heterozygous genotype while the males had a hemizygous dominant genotype. All offspring expressed the wild type phenotype†¦. Each of the Punnett squares are possible outcomes of offspring phenotypes based on the genotypes of the parents. By comparing our results to that of the Punnett square’s we will be able to determine, through process of elimination, whether or not the mutation is a dominant or recessive trait and if it appears through an autosomal or sex linked chromosome. Based on the phenotypes of the offspring, we can infer the identifications of the parental genotypes.

Why the court should have the right to impose a publication ban in Cana

Publication bans have been a part of the Criminal Code since 1988. A publication ban is a court law that prohibits trial information from leaving the case. Since these bans were first introduced in Canada, they have become a very useful tool in Common Law. These bans have been frequently used over the years for many purposes including avoiding the risk of adverse consequences to participants and for more accurate trial procedures. Having publication bans are beneficial, in every which-way, than not. These bans contribute positively to the environment of law and most importantly, the society within. This essay will outline why the court should have the right to impose a publication ban in Canada. It will support the debate that if Canada wishes to build towards a reputation of having trials handled efficiently, then it should not change the nature of these publication bans. It will portray the importance of these bans through a thorough explanation of how the bans work, and two solid arguments of the cause on the society and environment. First, this essay will discuss basics of publication bans and how they work. Then, this essay will point out how publication bans contribute to trial fairness in the court. Finally, this essay will touch upon how publication bans protect victims and those involved in the trials. The court, when needed, handles publication bans wisely and with care. Just like any other law, publication bans are put to use for positive outcomes and improvements, and the court assures this. Publication bans are considered to the court either by a request from a trial participant during a bail hearing, or by the decision of a judge, when he/she feels the ban is necessary (CBCN).

Financial Aid Appeal Essay

Dear Office of Financial Aid, My name is ——– and I am writing to appeal my suspension from financial aid. I hope that you will reconsider your decision and grant my financial aid. I would like to begin thanking you in advance for taking the time to read this letter and consider my request to reinstate my financial aid at Metropolitan State University at Denver. I admit, I took so many credit hours in college, but I would like to explain the reason. As Spanish person, and because I speak English as a second language, I had to take ESL(English as a Second Language) classes for my first two years (four semesters) at CCD (Community College of Denver). The ESL program was not something that I had chosen, but something that I had to get done in order to follow my general education. I did not mean to spent so much time in college and take so many credit hours, but I did not have other options. Now that I have completed the ESL program, I feel so excited and motivated about taking regular classes. I love being student at Metropolitan State University at Denver and it would mean so much to me if I was able to finish my degree and graduate at this school. I already had completed most of general course, I’m done with my Math and some major course. I am currently registered for next spring 2013 classes and a few classes for the upcoming to get done with my degree. Thank you for taking the time to read this letter, and I assure you that my education is, and will continue to be, my main priority. I just hope you’d help me achieve my goals quicker by reinstating my Financial Aid. Thank you for your time and consideration.

Essay on The Crusades - 908 Words

The Crusades A major turning point in Medieval history were the Crusades. The Crusades were a series of wars fought between the Christian Europeans and the Muslim Turks, which occurred between the years of 1096 to 1272. In this Holy War the Christians goal was to obtain the Holy Land from the Turks, in which they did not succeed. Although the Christians did not meet their goal, many positives did come out of their attempt. Due to the reason that they did not meet their goal, yet numerous positives came out of their effort, many refer to this as a successful failure. A main cause of the Crusades was the treatment of Christian pilgrims. They were robbed, beaten, and then sold. The main group of Turks, the Seljuk Turks, were threatening†¦show more content†¦He also thought that the land in the Middle East would be an outlet for the overpopulation in Europe. Lastly, he agreed to send the knights away because it would keep them busy fighting Muslims instead of one another; in addition he kept the knights away form causing troubles in the towns. There were both positive and negative effects of The Crusades, although the positives did outweigh the negatives. The two major negative effects were anti-Semitism and the orchestrated attacks by Venice. Many Crusaders in Europe were so religiously fuming, that they turned their anger towards the Jews. They would at times massacre a whole community as a result of their religious rage. During the fourth crusade, crusaders began fighting Christians instead of Muslims. After helping Venetian merchants defeat their Byzantine trade rivals in 1204, the crusaders captured and looted Constantinople. They actually ransacked the capital of the Byzantine Empire, the empire in which they began to fight for, not against. There also were many positive effects of The Crusades, one being the increase of trade. Even before the Crusades, merchants began to enjoy some of the luxury goods that were brought from the Byzantine Empire.
