The genetic difference between two Drosophila species, D. heteroneura and D. silvestris, as measured by nucleotide diversity, is about 1.8 percent. The difference between chimpanzees (Pan troglodytes) and humans (H. sapiens) is about the same, yet the latter species is classified in a different genera. In your opinion, is this valid? Explain why.

Problem 13
Textbook Question
We all carry about 20,000 genes in our genome. So far, patents have been issued for more than 6000 of these genes. Do you think that companies or individuals should be able to patent human genes? Why or why not?
Verified step by step guidance1
Understand the concept of gene patenting: Gene patenting refers to the legal protection granted to companies or individuals for isolated and identified sequences of human DNA, allowing them exclusive rights to use or commercialize these sequences.
Consider the ethical implications: Reflect on whether genes, as naturally occurring elements of the human body, should be owned or controlled by any entity, and how this might affect research, healthcare, and access to genetic testing.
Evaluate the impact on scientific research: Think about how gene patents might encourage or hinder innovation, collaboration, and the development of new treatments or diagnostic tools.
Analyze the legal and economic aspects: Consider how patents provide incentives for investment in biotechnology but may also lead to monopolies and increased costs for patients and researchers.
Formulate your position by weighing the pros and cons: Decide if you believe gene patenting promotes progress and benefits society or if it restricts access to fundamental biological information that should remain in the public domain.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Gene Patentability
Gene patentability refers to the legal ability to claim ownership over isolated or modified human genes. It involves determining whether naturally occurring genetic sequences can be patented or if only synthetic inventions related to genes qualify. This concept is central to debates on intellectual property rights in genetics.

Ethical Considerations in Genetics
Ethical considerations address the moral implications of patenting human genes, including issues of accessibility, fairness, and the impact on research and healthcare. It questions whether genes, as natural parts of human biology, should be owned or controlled by private entities.

Impact of Gene Patents on Research and Medicine
Gene patents can influence scientific research and medical innovation by either encouraging investment through protection or hindering progress due to restricted access. Understanding this impact helps evaluate the benefits and drawbacks of allowing gene patents in advancing healthcare.
