Genetic Drift Examples

Genetic Drift Examples Genetic Drift Genetic drift is a change in the frequency of an allele within a population over time. This change in the frequency of the allele or gene variation must occur randomly in order for genetic drift to occur. There are no environmental influences that cause genetic drift to occur. Examples of genetic drift are more evident in smaller populations of organisms. Examples of Genetic Drift: 1. The American Bison was hunted to near extinction and even today as the population has recovered, the result is a population of bison with little genetic variation 2. A population of rabbits can have brown fur and white fur with brown fur being the dominant allele. By random chance, the offspring may all be brown and this could reduce or eliminate the allele for white fur. 3. A mother with blue eyes and a father with brown eyes can have children with brown or blue eyes. If brown is the dominant allele, even though there is a 50% chance of having blue eyes, they might have all children with brown eyes by chance. 4. A bird may have an allele for two different beak sizes. Depending on which alleles show up in the offspring, genetic drift could cause one of the beak sizes to disappear from the population thus reducing the genetic variation of the birds gene pool. 5. A certain type of plant can produce blue or yellow flowers. During a fire, many yellow flowers are destroyed and now since blue is the dominant allele, the plant reproduces plants that only produce blue flowers.

Analysis Of Henrik Ibsen s A Doll s House Essay

Film and theatre are very closely related, however, it is their cinematic differences that allow you to tell them apart. When a director recreates a play for movie production, the structure often does not change, like the plot and characters, yet the array of things that one can change stylistically are infinite. When performing a play, it is difficult to have multiple scene changes causing a play director to follow the stage directions more step by step, allowing film directors to prosper in this category. Henrik Ibsen’s â€Å"A Doll’s House† is more enjoyable to read than watch because it gives you the freedom to picture things how the reader would perceive the author. Much like director, Patrick Garland, has done. He applied his ideas to Ibsen’s original to produce his version. Now, the question is why are the things he changed different? Is it accidental that this happens over that or is he trying to create significance to another moment. Through care ful review of each of these works, a reader can conclude that Garland has followed along Ibsen’s path as the play progresses, for there are two noticeable major changes. The conversations between Nora and Rank, discussing his death, and Nora and Torvald, discussing their inevitable downfall. Considering that there are multiple other accounts variations, the director was probably leading up to these moments.

The Business Of Americ The President Of The 1920 S

Calvin Coolidge the President in the 1920’s, otherwise known as the roaring 20’s said that â€Å"the business of America is business.. It’s safe to say that â€Å"business† for the first 100 years of founding our country was small business. 90 percent of Americans had fewer than 20 employees, but the businesses in America had almost no choice but to be a small business, due to lack in transportation, marketing, and banks weren’t big enough to support big businesses at the moment. Americans though preferred it this way, because then, and as well as today the people believed that it cultivates character, and strengthens democracy. Small business is vital to the overall economic strength and security of this country. (Conte, 2008) In the late 1800’s is when small business values and beliefs would be tested with the growth of railroads, telegraphs. Machinery, steam engines, and the rapid population growth. People from the time currency was created to this day are power and money hungry. They want to capitalize, become larger, bigger without regard or worry. This took a hit to small business across our fairly new nation. If you look at the history of U.S. business then you can figure out that every business started small. Example would be Pittsburgh’s Carnegie Steel Company, now known as U.S. Steel. Now the largest steel producing corporation in the United States of America. (Conte, 2008) Modern small businesses are now advanced in every way possible, thanks to modern

Alice in Quantumland free essay sample

Electrons have no distinguishing features except spin Upon falling into the quantum wonderland while in her living room, Alice finds herself faced with a new reality of existence that seems to baffle her. She is first met with some strange-looking dweller of the new and vastly strange wonderland that she could not make out. She politely introduces herself as Alice, thereby invoking a response from her companion to the effect that it was an electron. Alice also noted that nearby was another similar looking figure to the electron, to which the new acquaintance explained was a different electron. To Alice, the two electrons looked strikingly alike, down to the umbrella they seemed to have been carrying. Her new friend explains to her that the other electron is actually different; that is, it has a different spin. In essence, the two electrons have absolutely no distinguishing features except for their direction of spin. In the real world, however, things are quite the opposite. Two people, even identical twins, always seem to have distinguishing character traits, which are readily observable. This latter truth, however, is only implemented to the larger macro-world of classical mechanics, which was espoused by Sir Isaac Newton. 2. Heisenberg’s uncertainty principle Alice’s escapade continues to get more and more bizarre as she notices that her electron companions seemed to always be moving too fast. She in fact asks them to try and slow down a bit so that she can make out how they look like more clearly. As soon as one of her electron friends attempts to reduce his speed, he begins to expand and spread out, filling the entire space around him. This makes it even harder for Alice to discern how he really looks like. He then tells her that this is part of the standing rule; that they cannot slow down lest they get too cramped together into the entire space available. This concept is especially abstruse. It is almost as if the electrons increase in number when they slow down, but, in essence, they only occupy the entire space around. This phenomenon is called Heisenberg’s uncertainty principle. It means that it is impossible to ascertain the precise position and the precise location of a sub-atomic particle at the same time. In essence, Gilmore explicates that Alice cannot see the electron easily when it slows down since its speed is precisely known: it is zero. This is most certainly not the case in the macro-world of Newtonian classical mechanics where we live. Indeed, it is possible to know exactly where someone is and exactly how fast he or she is moving, both at the same time. 3. Pauli’s exclusion principle Another provocative phenomenon Alice encounters in the quantum wonderland is known as Pauli’s exclusion principle. This principle basically impedes any two subatomic particles to be characterized by the same quantum number. This means that they cannot be in similar quantum states. According to Gilmore, electrons are exactly identical and must therefore abide by the exclusion principle, which was described by Wolfgang Pauli. This meant that Alice’s electron companion could not occupy the same train compartment as its identical counterpart, with a similar spin. Such an elaborate description of the state of affairs at the quantum level is in direct violation of observed phenomena in the macro world of classical mechanics. In the classical world, two identical entities can indeed share the same compartment. Alice’s electron counterpart states that he cannot be doing the same exact thing as another identical electron. This is not verifiable in the observable world of Newtonian mechanics, where it is possible to have similar entities engaged in the same exact event. 4. Superposition Alice heads out to the Mechanics institute where she gets well acquainted with the concept of superposition. In essence, she learns that subatomic particles such as electrons can be in several different places at the same time. She precisely learns that the concept of superposition basically means that an electron is capable of doing all possible things to it. This is verified by the double slit experiment. The experiment yields the phenomenon of interference when electrons are shot out from an electron gun one at a time; they are shot in a beam through an obstacle with two slits and onto a screen. This experiment, and the resulting interference, indicates that each electron passes through the two slits at the same time and essentially interferes with itself. Similar to the other phenomena that Alice encounters, this one is also in direct violation of common sense judgments of observations in the macro-world. In essence, no observable entity in the real world of classical mechanics is capable of doing all things possible at the same time, let alone be in several different positions at the same time. 5. The Copenhagen interpretation and Schrodinger’s cat Alice proceeds to meet with a series of other unusual characters while in the quantum wonderland. One of the most intriguing characters she comes across is undoubtedly Schrodinger’s cat. Alice learns that Schrodinger had left a cat behind with some inhabitants of the quantum wonderland which he used as an experiment to test and prove some of the theories espoused within the larger field of quantum mechanics. Schrodinger set up an experiment in which the cat was to be placed inside a box with a flask of poison, a radioactive source and a mechanism that would ensure the poison is released in case if any radiation. According to Schrodinger’s analysis, the Copenhagen interpretation of quantum mechanics indicates that after some time, the cat is both dead and alive. Nevertheless, when the box is opened, the cat can only be either dead or alive but not both. This abstraction of quantum reality is tormenting to people who live in the macro world of classical mechanics. Things in this world are never in two different states concurrently.
