With all these at hand, you may be tempted to opt-out immediately. However, this top-notch guide seeks to make genetics essay writing as fun and as straightforward as possible. Ride along to see the magic!

What Is An Essay on Genetic Engineering?

Now, genetic engineering in itself is the use of biotechnology to manipulate an organism’s genes directly. Therefore, essays on genetics will require students to explore the set of technologies used to change cells’ genetic makeup. These include the transfer of genes within and across species boundaries to produce novel or improved organisms.

We have various areas of genetic engineering, such as:

  • Human genetic engineering definition: Deals with genetic engineering techniques applied to humans
  • Genetic engineering in plants: Concentrates on genetically modified plant species

Genetic engineering is mostly applied in medicine and thus its technicality. I know this is a field that most students approach with reverence and uttermost humility. Nonetheless, it doesn’t have to be that way. The next few lines might change your opinion on genetic engineering forever!

Why is genetic engineering necessary?

Importance of Genetic Engineering

It is essential in the following ways:

  1. Ensures that seed companies can protect modified seed varieties as intellectual property.
  2. Leads to production o organisms with better traits
  3. Helps maintain the ecosystem

You can see why this field is unavoidable regardless of the negative talk behind it.

Genetically Engineering Plants and Animals – Essay Sample

Young in practice, a little over forty years old, genetic engineering has provided the scientific community with an abundance of knowledge once thought absurd. Genetic engineering means deliberately changing the genome of an organism to acquire some desired traits during its cultivation. On the whole, genetic engineering has a multitude of advantages and disadvantages when it comes to using it on animals and plants; the most prominent advantages include disease resistance, increased crop yields, and a decrease in need for pesticides and antibiotics, whereas disadvantages include the potential for emergence of stronger pathogens, as well as various unexpected consequences. This current paper discusses the pros and cons of using genetic engineering on plants, animals, and provides a synthesis, arguing that, despite its disadvantages, it still serves as a pivotal advantage not only within the scientific community, but also society.

The Advantages of Using Genetic Engineering

The impact of genetic engineering on society can be seen at various aspects, affecting various aspects of social and physical organic life, especially in terms of human beings. The practice consists of the specific selection and removal of genes from organic organisms and inserting them into another. The practice, though still young in practice and not yet deemed completely socially acceptable, makes the possibility of curing diseases once thought incurable a reality, thereby inherently improving the life of both humans and non-human animals. It has many positive effects on society, an example being in Uganda bananas, a main source of caloric intake, are susceptible to the emergence of new diseases that affects their production because of the disease’s potency. Ugandan scientists have successfully used a genetic modification, inserting a pepper gene into bananas, which prevents the fruit from getting the disease (Bohanec, 2015). Furthermore, through genetic engineering, tissue, skin cells, and other forms of organic matter can be grown and used in replacing damaged, worn, or malfunctioning organs and tissues thereby prolonging human life and benefiting their quality of life. The practice helps better advance both the scientific and medical field, both of which are essential in discovering how to better life on Earth.

Genetic engineering, as previously mentioned, can be used to grow and replace damaged tissue or organs, aiding in the betterment and prolonging of human life; it can cure diseases once though incurable, an example being AIDS and cancer. Millions of people around the world suffer from AIDS and cancer, both posing a severe risk to the overall health of the person. More than 900,000 lives were taken by AIDS in 2017 (UNAIDS, 2018). Similarly, over 600,000 were taken by cancer in the following year (NIH, 2018). Genetic engineering makes the possibility of eradicating these diseases a reality. In theory, genetic engineering can help those who suffer from these diseases live longer, healthier, fuller lives by eradicating the disease in its entirety. Though it would not be an easy feat, nor a cheap one, it could still help further advance and better human life and prolong the human life span. People would no longer live in fear of dying from these prolific diseases. Furthermore, genetic engineering, despite the naysayers and opposers of the practice, is another step in organic evolution. From plants to animals, the practice has the chance to achieve strides within scientific history that can greatly benefit the planet in its entirety. From eliminating hunger, to eradicating once prolific diseases, genetic engineering can provide a better, longer, and higher quality of life and tackle bounds once thought impossible the scientific community.

Genetically engineered plants and animals may provide a wide array of benefits that might be pivotal for humanity in the modern world. These benefits include the possibility of developing such plant cultivars that would be resistant to a wide variety of pathogens and diseases caused by microorganisms such as viruses (Ginn, Alexander, Edelstein, Abedi, & Wixon, 2013). If such plant cultivars are created, it might become unnecessary to use chemicals in order to battle these plant diseases. This is clearly a major benefit, since it means better preserving the natural environment and avoiding the use of chemicals that may contaminate soils and waters, as well as kill wildlife.

The Disadvantages of Using Genetic Engineering

The use of genetic engineering to alter plants and animals used in agriculture and husbandry may also have a variety of adverse consequences. For instance, it should be noted that high rates of resistance to disease might have a serious flip side. More specifically, the pathogenic microorganisms (such as bacteria and viruses) can usually mutate quickly in order to adapt to the new conditions. This means that if new cultivars or breeds of plants or animals with high resistance to diseases are created, the pathogens may adapt to these changes in their “hosts” and turn stronger, thus becoming capable of infecting the new cultivars or breeds (Ayres, n.d.). This might again necessitate the use of chemicals or antibiotics; only now stronger drugs or pesticides would be needed. In addition, the old cultivars or breeds may also become infected by the new microorganism strains, and these strains will probably cause more severe diseases in the “original” plants and animals and will be more difficult to cure or prevent.

Another negative possibility is accidentally creating some invasive species that may harm the local ecosystems. For instance, if new plants are made in such a manner that the local species of animals cannot eat them, and then humans lose control over their growth, the new plants may pose a danger to the original plants growing in the given ecosystem, therefore disrupting the ecosystem. For example, in 1984 a patch of seaweed labelled as Caulerpa taxifolia was bred with another robust strain of seaweed identified by scientists as Caulerpa taxifolia (Vahl) C. Agandh. The initial objective was to breed an aquarium plant, however, after a sample escaped in 1984 into the Mediterranean Sea, being found off the coast of both the United States and Australia in 2000, it was found that the strain’s taste was subpar to marine wild life. It was eventually poisoned by the California state government to avoid further damage to marine life and the marine ecosystem and was consequently outlawed by hundreds of countries. The World Conservation Union named it one of the 100 World’s Worst Invasive Alien Species, despite it being manmade (Cellania, 2008).

Finally, there is always the risk of “going too far” when practicing genetic engineering (Bruce & Bruce, 2013). Indeed, it should be noted that the humanity has used various methods of cultivation for millennia in order to breed for specific traits. For example, in 1956, Warwick Kerr, a Brazilian geneticist, imported an aggressive breed of African honeybee to breed with a European species to aid in the decreasing bee population epidemic. Provoked by even the smallest of instigation, after over 26 swarms of the aggressive bee escaped from the apiary in Sao Paulo, they wreaked havoc in North and South America, found in the United States in the early 90s. Nevertheless, genetic engineering is a fast and radical method to change organisms, and very little, if any, data is available to predict the potential adverse impacts of its utilization. It may be difficult to tell when (if at any point) one must stop the process of genetic engineering to avoid unexpected adverse influences of its utilization.


Genetic engineering, despite its disadvantages, can help progress humanity in ways that once seemed impossible. With the environmental and physical epidemics surrounding the planet, the practice can serve as a benefit to resolving the hunger crisis, the preservation of endangered plant and animal species, bringing certain species back from extinction, and so much more. It should be stressed that the utilization of biotechnology and genetic engineering may bring a wide array of significant benefits, which may be of great use to the humanity nowadays. The creation of breeds and cultivars which are immune to disease, resistant to harsh environmental conditions, are cheap to grow, and provide better nutritional value for people might be extremely helpful in reducing the amount of chemicals, pesticides, and antibiotics needed to grow these animals or plants, and, consequently, to help preserve the environment. However, it should also be remembered that genetic engineering might have a wide array of adverse impacts, such as the emergence of new, stronger pathogens, the creation of invasive species, and a multitude of negative consequences that no one knew to expect.
