Final answer:
Twenty years ago, decoding DNA at home was not feasible due to the lack of available technology and the need for specialized equipment. Today, the availability of medical genetic tests to the public has made home DNA testing for rare medical conditions possible. However, ethical considerations concerning the use of genetic information remain a topic of discussion.
Step-by-step explanation:
Decoding DNA at Home: Now vs. 20 Years Ago
Two decades ago, the decoding of DNA in a non-laboratory setting would have been highly improbable for most people. At that time, the tools and technologies necessary for DNA sequencing were mostly confined to well-equipped research laboratories. Decoding a child's DNA to identify a rare medical condition would involve expensive equipment and specialized expertise in molecular biology.
Today, genomic technologies have evolved considerably, and there are companies that make it possible to order medical genetic tests online. These tests can determine an individual's risks for certain genetic diseases, including those that follow Mendel's Theory of Inheritance. Furthermore, advancements in biotechnology have reached a point where we can even consider therapies that may fix faulty genes responsible for genetic disorders.
Genetic testing and analysis have become far more accessible, with kits available for use at home. This includes testing for paternity, identifying genetic risks, and contributing to personal and forensic applications. Nonetheless, the social and ethical implications of such widespread access to our genetic information are subjects of ongoing debate.
