Gregor Mendel's Fruit Flies Introduction From simple heredity experiments with garden peas, to cloning sheep, the field of genetics has come a long way. Now we are closer to mapping out the human genetic map due to advances in technology, and years and years of research. Perhaps the most influential and groundbreaking scientist, Gregor Mendel, he was responsible to provide a path to where genetics is now today with his experiments of garden peas. In lab, fruit flies were crossed to observe inheritance patterns in their offspring. The motivation for this was to further understand how genes and characteristics are inherited. To use fruit flies would be much more effective and easier because of a couple of reasons. The genetic makeups of the flies only consist of 4 pairs of chromosomes. This makes it easier to spot characteristics, and is easily distinguishable. Another plus to using flies is that fruit flies can produce a whole new generation of offspring in two weeks, which is very convenient for researchers. This is why files are used instead of humans, but not only time, ethics have also been a major, if not the most important factor. The traits observed here in this experiment were the wing types, whether vestigial or normal, and the eye color, whether brown or white. The genotype of the vestigial wing was a homozygous recessive vv. The normal wings were either Vv, or VV. The eye color was denoted by the genotype BB, and Bb for brown, and bb for...

    Genes are expected to give offspring hereditary similarities to the parent. However, this was not known and Gregory Mendel asked himself what was passed on by parents to their offspring that is the basis for similarity. Mendel would go on through experiments with pea plants to answer short questions. The answers were short as well as to say that the passing of characteristics from parents to the offspring is throug...

  • The Green Peas Recessive And The Pea Plant Experiment

    1086 Words  | 3 Pages

    Gregor Mendel was born into a German family, as a young man Mendel worked as a gardener and studied beekeeping. In his later life Mendel gained his fame as the founder of the modern science of genetics. The research that was his claim to fame was his pea plant experiment. Mendel looked at seven different characteristics of the pea plants. For example with seed colors when he bred a yellow pea and green pea together their offspring plant was always yellow. Though, in the next generation of plants, the green peas reemerged at a 1:3 ratio. To explain what he had discovered, Mendel put together the terms “recessive” and “dominant” in reference to specific traits. Such as, in the previous example the green peas were recessive and the yellow peas

  • Analysis Of Machiavelli's The Prince

    764 Words  | 2 Pages

    Throughout Machiavelli’s novel, we encounter several specific instances in which the author gives explicit advice to would be or currently serving princes and rulers of nations. Much of this advice can be easily translated to world leaders in the present day, including the President of the United States. However, some of the advice that Machiavelli gives out are things that often times don’t apply to current world leaders. As I explore the novel, I can’t help but imagine several real life politicians using some of the methods of ruling discussed by Machiavelli, with the true of definition of Machiavellianism being “the employment of cunning and duplicity in statecraft or in general conduct.”

  • Machiavelli's The Prince: Still Relevant after All These Years

    2155 Words  | 5 Pages

    Written almost 500 years ago, Niccolo Machiavelli’s “The Prince” brings forward a new definition of virtue. Machiavelli’s definition argued against the concept brought forward by the Catholic Church. Machiavelli did not impose any thoughts of his own, rather he wrote from his experience and whatever philosophy that lead to actions which essentially produced effective outcomes in the political scene of Italy and in other countries. While Machiavelli is still criticized for his notions, the truth is that, consciously or subconsciously we are all thinking for our own benefit and going at length to achieve it. On matters of power where there is much to gain and a lot more to lose, the concept of Machiavelli’s virtue of “doing what needs to be done” applies rigorously to our modern politics and thus “The Prince” still serves as a suitable political treatise in the 21st century.

  • Gilgamesh Leadership Essay

    1009 Words  | 3 Pages

    Machiavelli in his famous book “The Prince” describes the necessary characteristics for a strong and successful leader. He believes that one of the most important characteristics is to rule in favor of his government and to hold power in his hands. Power is an essential aspect of Machiavelli’s theory, and a leader should do whatever it takes to keep it for the safety of his country because “the ends justifies the means.” To attain and preserve the power, a leader should rather be feared than loved by his people, but it is vital not to be hated. As he states, “anyone compelled to choose will find far greater security in being feared than in being loved.” If a leader is feared, the people are less likely to revolt, and in the end, only a threat of punishment can guarantee obedienc...

  • Machiavelli vs. Lao-Tzu

    284 Words  | 1 Pages

    Machiavelli believes that a government should be very structured, controlled, and powerful. He makes it known that the only priorities of a prince are war, the institutions, and discipline. His writings describes how it is more important for a prince to be practical than moral. This is shown where he writes, "in order to maintain the state he is often obliged to act against his promise, against charity, against humanity, and against religion" (47). In addition, Machiavelli argues that a prince may have to be cunning and deceitful in order to maintain political power. He takes the stance that it is better for the prince to be feared than loved. His view of how a government should run and his unethical conduct are both early signs of dictatorship.

  • Machiavelli and Rousseau's Views on Human Nature and Government

    558 Words  | 2 Pages

    Machiavelli’s views were drastically different from other humanists at his time. He strongly promoted a secular society and felt morality was not necessary but stood in the way of a successfully governed state. He stated that people generally tended to work for their own best interests and gave little thought to the well being of the state. He distrusted citizens saying, “In time of adversity, when a state is in need of its citizens, there are few to be found.” In his writings in The Prince, he constantly questioned the citizens’ loyalty and warned for the leaders to be wary in trusting citizens. His radical and distrusting thoughts on human nature were derived out of concern for Italy’s then unstable government. Machiavelli also had a s...

  • Role of Colour in Impressionism

    1686 Words  | 4 Pages

    In this essay, I shall try to examine how great a role colour played in the evolution of Impressionism. Impressionism in itself can be seen as a linkage in a long chain of procedures, which led the art to the point it is today. In order to do so, colour in Impressionism needs to be placed within an art-historical context for us to see more clearly the role it has played in the evolution of modern painting. In the late eighteenth century, for example, ancient Greek and Roman examples provided the classical sources in art. At the same time, there was a revolt against the formalism of Neo-Classicism. The accepted style was characterised by appeal to reason and intellect, with a demand for a well-disciplined order and restraint in the work. The decisive Romantic movement emphasized the individual’s right in self-expression, in which imagination and emotion were given free reign and stressed colour rather than line; colour can be seen as the expression for emotion, whereas line is the expression of rationality. Their style was painterly rather than linear; colour offered a freedom that line denied. Among the Romanticists who had a strong influence on Impressionism were Joseph Mallord William Turner and Eugéne Delacroix. In Turner’s works, colour took precedence over the realistic portrayal of form; Delacroix led the way for the Impressionists to use unmixed hues. The transition between Romanticism and Impressionism was provided by a small group of artists who lived and worked at the village of Barbizon. Their naturalistic style was based entirely on their observation and painting of nature in the open air. In their natural landscape subjects, they paid careful attention to the colourful expression of light and atmosphere. For them, colour was as important as composition, and this visual approach, with its appeal to emotion, gradually displaced the more studied and forma, with its appeal to reason.

  • The Principles Of Machiavelli Exposed in The Prince

    512 Words  | 2 Pages

    Machiavelli's views have been misinterpreted since his book was first written, people take him in the wrong way, and are offended by what he says. Careless readers take him in a completely wrong way, such as they think that he believes that the end justifies the means, that a leader should lie to the people, and that a ruler has to rule with force. In actuality, Machiavelli means no such thing, he says that there are times when the common good outweighs the means, and the morality of a rulers actions. He also says that you cannot be loved by everyone, so try to be loved and feared at the same time, but of the two, choose to be feared. The Prince is considered to be one of the most important of nonfiction literature written in the history of mankind. It gave an accurate and truthful description of the method of governing.

  • Renewable Energy: A Bright Future

    697 Words  | 2 Pages

    In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.

    Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
