Describe the economic benefits for selective breeding,
Breeding last few years ago was never this high tech as it is today. You were not able to put genes you want into other animals who you wanted it in. Selective breeding is the process by which humans breed other animals and plants for particular traits. Mostly, different that are selectively bred are domesticated, and the breeding is normally done by a good or pro breeder. Bred animals are known as breeds, while bred plants are known as many different others as well. Selective breeding is a modern agricultural technique used to genetically create or make better and genes you want characteristics in plants and animals. With being able to put gene in, this is usually accomplish through controlled breeding of high-yield plants and animals. The advantages of selective breeding include increased work/labor and the ability to rid future offspring of disease and disability. The disadvantages include a loss of genetic variety and possible difficulties and discomfort in the animals' lives. describe economic and social(ethics -is it right or wrong) benefits/ risks for genetic engineering.
The benefits/risks of antibiotic development and its use in crops/livestock.
Genetic engineering is often been known as a crucial part of the solution to the agricultural challenges of the 21st long long ago. One benefit for this is engineered crops have provided benefits in some areas, though these benefits tend to come with problematic tradeoffs. With different plants being put inside different plant genes allows more new plants or stronger plants.

...ch other to make involuntary movements (controlling each others bodies). Clearly we seem to be picking up the pace. There is almost an exponential increase in regards to technology as the years progress. But what impact will it have on us? How will this affect our planet? What have we learned from our past that will allow us to make proper/accurate simulations about the future.You will now write a 5 paragraph essay, by drawing upon information from our past and present (Information on Genocide - from reading, Guns, Germs, and Steel, current issues with genetic engineering, global warming, and biotechnology. Identifying key problems. Speculate about their impacts in the future, then talk about ways to solvethem at this later date. This is relatively open ended response so feel free to be creative in your response as long as it holds to the pretense above.
Modern biotechnology was born at the hands of American scientists Herb Boyer and Stain Cohen, when they developed “recombinant deoxyribonucleotide, (rDNA), [1] for medicinal purposes. Subsequently, biotechnologists started genetically engineering agricultural plants using this technology. A single gene responsible for a certain trait, from one organism (usually a bacterium) is selected altered and then ‘spliced” into the DNA of a plant to create an agricultural crop consisting of that...
The first genetically manipulated food was tomatoes, they entered markets in 1994. Tomatoes are being planted all over the world. Scientists have been studying new ways to improve tomato harvesting and what better way to do so than genetic manipulation. The aim in genetically manipulating tomatoes and mostly every other crop is to introduce a new trait to the plant which does not occur naturally in the species in order to enhance its beneficial traits for us humans. In this procedure, breeders must know exactly which gene(s) they need or else it might affect the giving organism and the receiving organism. Then they isolate those gene(s) of interest with a restriction enzyme that cuts DNA into small fragments. The desired gene(s) must be copied from gene(s) that were extracted. This is called gene cloning. The gene may be modified slightly to work in a more desirable way once inside the recipient organism. The recipient organism is basically the receiving organism. The new gene(s), called a transgene is delivered into the cells (especially the reproductive cells) of the r...
This process is seen mostly in agriculture. It is because of artificial selection that we have the domesticated plants and livestock that we eat. In the case of canines, they were originally bred to become working and hunting dogs in agriculture. Later on they were bred as companion animals. The different variations of domesticated dog will be discussed later. The down fall of artificial selection is that it decreases variation in a species. Pure bred dog are highly susceptible to many different disorders and disease because of the lack of variation in their genotype. With these two processes, today we have friendly canine
When talking about the future of technology, one can only imagine what it will be down the road. The future of technology evokes many questions about the preservation of human existence, human advancement and intelligence. Some writers even discuss their positions on the future of technology and human kind. Writers such as James J. Bell, who explains the theory of the ‘Singularity’. In summary, he states that the rate of technological advancement, compared to human intelligence, will one day reach the ‘singularity’ were it will surpass the human mind (pg. 52). We may never know if technology will ever have the power to surpass the human intellect or what the consequences will be if it does attain these capabilities. Will humans still maintain control over them, or will they control us? Theses eight articles illustrate the implicit and explicit control that technology holds over humans in the future.
Genetic Engineering is essentially altering / adding new DNA into an organism, to provide that organism with more desirable traits. Process - desired gene is isolated with restriction enzymes from organism, and then extracted. The gene then undergoes PCR (polymerase chain reaction) where the gene is sequenced and then copied multiple times, to be re - inserted into the new organism (transgenic). This process is commonly used to provide plants with more desirable traits (e.g. less reliance on water) and can be used just as easily to provide humans with the traits that they themselves desire (e.g. blonde hair and blue eyes). However, medical complications and ethical issues prevent such procedures from occurring, as the theory and practice is still very much in its infancy, and as there is no glass ceiling as such in this particular field of engineering, resulting in countless possibilities that the world may not yet be prepared for.
The process of selective breeding starts with a human selecting a pair of animals that have a desired trait wanted in the offspring.Natural selection works by nature selecting what animals are better at surviving
Selective breeding A breed is a particular set of domestic animals or plants having uniform look and behavior, that differentiate it from other animals or plants. Domestication is the process whereby a population of living organisms is changed at the genetic level, through generations of selective breeding, to accentuate traits that ultimately benefit humans. The deliberate breeding of animals and other species to obtain required features by human beings is called selective breeding. It includes breeding methods such as inbreeding, line breeding, etc. The animals that are produced are tamed, and the breeding is usually done by an expert breeder.
It has even gotten to the point where humans question their sense of place in the universe and have searched for extraterrestrial life. These have been displayed in literature and arts. People have used these technological advances to affect their social lives and problems such as pollution from cars, factories that affect atmosphere, being able to foresee natural disasters before they happen which is able to give people enough time to prepare and even evacuate the possibly affected areas, and the disintegration of the North and South
These methods, however, have been limited to naturally occurring variations. Recent advances in genetic engineering have made it possible for scientists to precisely control any genetic changes introduced into an organism. Genes from one species can, through genetic engineering, be incorporated into an entirely different species. When in reality we need to let nature run its course instead of force breeding and making everything about people and what benefits them instead we need to think about the animals we are
Technology is an important issue that my generation will face in the coming years if it is used inappropriately. Albert Einstein states his input on how technology will be an issue: “I fear the day that technology will surpass our human interaction. The world will have a generation of idiots”. Many people say that technology will affect people’s ability to think properly and claims that we will have a generation of people who are ignorant compared to earlier generations. Technology has shaped how people live their lives on a regular basis and it defines my generation as the technology generation. Technology has changed how we do things in our daily lives and has become a large part of our daily lives and has impacted each
New technological advances are being mad every day, especially in genetics. With great innovations comes concerns whether it will have a good cause or be used for bad intentions. One of these is eugenics, the idea to improve genetic composition in humans most specifically in future fetuses. The idea started in 1883 by Sir Francis Galton who wanted to selectively breed humans using desired traits to create a perfect human race. This lead to many unethical moments in history such as the sterilization of unfit humans in the 19th century as well as Hitler’s use of eugenics during WWII. However, current use helps identify possible inherited diseases/conditions in unborn children and remove those traits from the DNA. Although eugenics has been used
Therefore, what exactly is selective breeding? And how does it work? This is done by a professional breeder takes two animals/plants with the traits he wants and mates them. The offspring can either be a crossbreed, or hybrid. “This is usually done by crossing two members of the same species which possess dominant alleles for particular genes,
Genetically Modified Organisms (GMOs), are the result of applying genetic engineering to crops. This is where the genetic information of an organism is altered to a specific desire called artificial selection. The genes of an organism are changed in order to make them more suited to survive in the environments they are in. Plants, as well as animals, are able to be genetically engineered. This innovative research will broaden the horizon of scientific technology as the world knows it.
Eugenics refers to the science of regulated breeding to increase the occurrence of favorable traits, decrease that in undesired ones and overall, improve a species. During the years 1890- 1930- known as the progressive era, the science sparked a movement of groups in Britain and the US who supported this controlled reproduction to achieve an improved human race in their society. During this time it was highly supported as it was believed to be a method to eliminate the increasing criminals, poor and incapable workers in society. The progressive era was a time of strong desires for reform to rid of industrial and social problems in society. The sudden influx of scientific
We live in a world that is constantly changing and advancing thanks to technological advancements, especially in the field of molecular genetics. Today, we are discovering and implementing new ways to overcome the ill-fated symptoms developed as a result from poor health or accidents. We are also making advancements in the field of agriculture thanks to molecular genetics. As we all know, food is an essential entity in our lives and is abundant as well as relatively easy to obtain here in the United States. However, as good as it may sound, this is not necessarily true for developing countries. Many people in developing countries receive very little food, if any, due to its scarcity. It is estimated that in Asia alone, close to 800 million people go to bed hungry every night due to food shortage. This problem can be alleviated by turning to the production of genetically modified organisms (a.k.a. GMOs).
