Question

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.

Answer 1

Selective breeding allows for the natural process of species evolution to occur, while genetic modification involves directly altering the genetic makeup of an organism. The advantages of selective breeding include the preservation of natural diversity within a species, as well as the potential for increased disease resistance and adaptability to changing environments. However, the disadvantage is that it is a slower process and relies on chance mutations. In contrast, genetic modification offers more precise control over specific traits but can result in unknown long-term effects on ecosystems and human health. A person may choose selective breeding for ethical reasons, such as minimizing harm to animals, while a person might choose GMOs for the potential benefits, such as increased crop yields and disease resistance.
