Compare and contrast the advantages and disadvantages of selective breeding versus genetic modification. Why might a person choose to use selective breeding over genetic modification? Why might a person choose to create a GMO over a selectively bred organism? Use three to five sentences to formulate your argument.(4 points)
Advantages of selective breeding include working within existing gene pool and gradual improvement, while disadvantages include limited genetic variation and unintended consequences. Genetic modification allows for precise gene manipulation and creation of traits unattainable through selective breeding. A person may choose selective breeding for gradual improvement within existing gene pool, while opting for genetic modification for precise trait creation. Factors like speed, precision, and potential risks influence the decision between the two methods.
Selective breeding involves breeding animals or plants with desirable traits to create offspring with those traits, while genetic modification involves directly manipulating an organism's genes to achieve a desired outcome.
Advantages of selective breeding include the ability to work within a species' existing gene pool and the potential for gradual improvement over generations. Disadvantages include limited genetic variation and the potential for unintentional effects on other traits.
On the other hand, genetic modification allows for precise modification of specific genes to introduce new traits or improve existing ones. This can be beneficial for creating organisms with traits that cannot be achieved through selective breeding. However, concerns about environmental and health risks associated with GMOs may lead some to prefer selective breeding.
Ultimately, the choice between selective breeding and genetic modification may depend on the specific goals and constraints of the situation, with considerations such as speed, precision, and potential risks influencing the decision.
