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
Selective breeding has been used for thousands of years and offers several advantages. It allows for the preservation of desirable traits within a species, promoting genetic diversity and adaptability. Additionally, selective breeding can be conducted on a small scale and is cost-effective. However, it is a slow process, relying on natural genetic variations, and may lead to unintended negative traits being selected for.
On the other hand, genetic modification enables the precise manipulation of specific genes, creating organisms with desired traits quickly. It can target specific challenges such as disease resistance or increased yield. However, genetic modification is a complex and expensive technique, and there are concerns about its long-term effects on ecosystems and biodiversity.
A person might choose selective breeding over genetic modification due to its simplicity and low cost. If they are looking for small-scale improvements or gradual changes in a species, selective breeding is a viable option. In contrast, creating a GMO might be chosen when specific traits need to be introduced to an organism rapidly, or when selective breeding alone cannot achieve the desired outcome, such as introducing traits from one species into another. Ultimately, the choice between selective breeding and genetic modification depends on the desired outcome and the resources available.
