Why might a person choose to create a GMO over a selectively bred organism? Use three to five sentences to formulate your argument.(4 point
Selective breeding and genetic modification are both methods used to alter the genetic traits of organisms. However, they differ in terms of advantages and disadvantages.
Selective breeding, also known as artificial selection, is a natural breeding technique where desirable traits are chosen and passed on through generations. It is advantageous as it preserves the natural genetic makeup of organisms and is generally accepted by society. However, it is time-consuming and less precise compared to genetic modification.
On the other hand, genetic modification involves inserting foreign genes into an organism's DNA to introduce specific desired traits. This method allows for precise modification, faster results, and the ability to introduce traits from different species. However, it raises concerns about the safety of genetically modified organisms (GMOs) and potential environmental impacts.
A person might choose selective breeding over genetic modification if they prioritize maintaining the integrity of natural genetic makeup and cultural heritage. Selective breeding allows for the preservation of unique traits and enables a more gradual change over time.
Conversely, a person might choose to create a GMO if they seek a quicker and more precise alteration of specific traits, especially if those traits are not present in the organism's natural gene pool. Genetic modification offers the possibility of introducing resistances to diseases, improving crop yields, or developing organisms with enhanced characteristics for various purposes.
In conclusion, the choice between selective breeding and genetic modification depends on the individual's priorities and requirements. Selective breeding is a more conservative and time-consuming method that preserves natural genetic makeup. Genetic modification, while faster and more precise, carries uncertainties and potential risks but offers the possibility of introducing specific traits not found naturally.
